Can someone please help me???

a is 3/4
b is -8
c is -2
d is 3

-b[a + (c-d)^2]

-(-8)[3/4 + (-2 -3)^2]

8 [3/4 + (-5)^2]

8 [3/4 + 25]

8 [25.75]

206

=======================================

Work Shown:

a = 3/4

b = -8

c = -2

d = 3

----------------

c-d = -2-3 = -5

(c-d)^2 = (-5)^2 = 25

a+(c-d)^2 = 3/4 + 25 = 3/4 + 100/4 = 103/4

-b * [ a + (c-d)^2 ] = -(-8)*103/4 = 8*103/4 = (8/4)*103 = 2*103 = 206

----------------

Another way to show the steps could be

Which is more or less the same thing as the previous section.

----------------

So ultimately,

when a = 3/4, b = -8, c = -2, and d = 3.
