Question
Algebraic expressions (Part 1)INTRODUCTION TO ALGEBRAEvaluate the following expression if x=3𝑥=3, without using a calculator.−5x+6+x2−5𝑥+6+𝑥2Answer: 2 attempts remaining
Solution
To evaluate the expression -5x + 6 + x^2 when x = 3, you substitute the value of x into the expression.
Step 1: Substitute x = 3 into the expression -5(3) + 6 + (3)^2
Step 2: Simplify the expression -15 + 6 + 9
Step 3: Add the numbers together -15 + 6 + 9 = 0
So, the value of the expression -5x + 6 + x^2 when x = 3 is 0.
