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.
