Ineed on #2 if a=-1/2,b=4,and d=-3, what is the value of 3ab^2-d^3/a

First, you should substitute the variables for their value in the expression.

= [ 3 (-0.5) (4)² - (-3) ] / (-0.5)

= [ 3 (-0.5) (4)² + 3 ] / (-0.5)

= [ 3 (-0.5) (16) + 3 ] / (-0.5)

= [ (-1.5) (16) + 3 ] / (-0.5)

= [ (-1.5) (16) + 3 ] / (-0.5)

= (-24+3) / (-0.5)

= -21 / -0.5

= 42
