Answer: Evaluate 2x2−3x+8 when x=−4 .
Substitute −4 for x. 2(−4)2−3(−4)+8
Simplify exponents. 2(16)−3(−4)+8
Multiply. 32−(−12)+8
Subtract. 44+8
Add. 52
Now we can evaluate expressions that include multiplication and division with integers. Remember that to evaluate an expression, substitute the numbers in place of the variables, and then simplify.
