Evaluate for x = -2 , y = -3 , and z = 5

To solve this question you would plug in the values given into the expression making sure that you include any negative signs and obey order of operations. The expression 8x(yz-1) would become 8(-2) ((-3)(5)-1).

(-3)(5)=-15, so the expression would change to 8(-2)(-15-1).

-15-1=-16

8(-2)=-16

-16*-16=256
