How to Solve a Evaluating Expressions Problem
2x² – 3x + 1 when x = 2
Time needed: 2 minutes
Step-by-step solution to evaluate the algebraic expression 2x² – 3x + 1 when x is equal to 2.
- Identify the expression and variable
Expression: 2x² – 3x + 1. Value of x is given as 2.
- Substitute the value of x
Replace x with 2 in the expression: 2(2)² – 3(2) + 1
- Apply exponent
2(4) – 6 + 1
- Multiply
2 x 4 = 8 – 6 + 1
- Add and subtract
8 – 6 = 2, then 2 + 1 = 3
How do you evaluate an expression?
To evaluate an expression, you substitute the given values for the variables and perform the necessary operations (addition, subtraction, multiplication, division, etc.) according to the rules of arithmetic. The goal is to simplify the expression to a single number.
How do you assess expressions?
Assessing expressions involves understanding the problem, substituting the values of variables into the expression, and performing the calculations. You need to follow the proper order of operations (PEMDAS) to simplify the expression and arrive at the correct result.
What are the rules for evaluating expressions?
When evaluating expressions, the main rules to follow are:
1. Substitute: Replace variables with their given values.
2. Order of Operations: Follow PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to simplify the expression step by step.
3. Simplify: Perform calculations in the correct sequence and simplify the expression to its final value.
What is the first step to evaluate expressions?
The first step in evaluating an expression is to substitute the given values for the variables into the expression. Once you’ve done that, you can begin simplifying the expression according to the order of operations.
How do you identify expressions?
An expression is a mathematical phrase that contains numbers, variables, and operations (such as addition, subtraction, multiplication, or division). You can identify an expression by its lack of an equality sign. It does not make a statement or compare anything—it simply represents a quantity.
How to evaluate the expression on fractions?
To evaluate expressions with fractions, treat the fractions just like any other number. Substitute the fraction into the expression and perform the same operations. If the fraction involves addition, subtraction, multiplication, or division, simplify it by finding a common denominator (for addition or subtraction) or multiplying/dividing the numerators and denominators accordingly.
What is the correct order of operation when evaluating an expression?
The correct order of operations is:
1. Parentheses (P): Simplify expressions inside parentheses first.
2. Exponents (E): Solve exponents or powers.
3. Multiplication and Division (MD): From left to right.
4. Addition and Subtraction (AS): From left to right.
5. This is often remembered by the acronym PEMDAS.
What are the steps in evaluating algebraic expressions?
The steps to evaluate algebraic expressions are:
1. Substitute the values of the variables into the expression.
2. Simplify the expression by following the order of operations (PEMDAS).
3. Perform calculations as required, such as multiplying, dividing, adding, or subtracting.
4. Get the final result, which will be a number.
How to evaluate expressions with parentheses?
When you have parentheses in an expression, simplify the part inside the parentheses first. If there are operations inside the parentheses, follow the order of operations (PEMDAS) until you’ve simplified that section. Then, continue with the rest of the expression.
What are common mistakes when evaluating expressions?
Common mistakes include:
1. Forgetting the order of operations (PEMDAS) and performing addition before multiplication, for example.
2. Not simplifying parentheses first, which can lead to incorrect results.
3. Misplacing negative signs during substitution or calculation.
4. Confusing exponents with multiplication, leading to incorrect evaluations.
How do you evaluate multi-variable expressions?
To evaluate multi-variable expressions, substitute each variable with its corresponding value and simplify the expression using the order of operations. Treat each variable just like a number, and perform the operations step by step.
