Question 1085295
<font color="black" face="times" size="4">The tutor @MathTherapy is correct. The answer is 68. 


The tutor @addingup mistakenly computed 5*(-1)*(2)^2*3 to get -60 when instead should have done 5*(-2)^2*3 to get 60. Notice how the negative inside the parenthesis. We're squaring ALL of 'a' including the negative.</font>
