F(a)=-2a^2 - 5a^4
if a=-3
f(-3)=-2(-3)^2 - 5(-3)^4
=(-2*9) - (5*81)
=-18 - 405
=423

The dice could either roll 6 and 5 or 5 and 6 which gives us the probability of 2/36.
Answer:
C. a = 3
b = 7
c = -20
Step-by-step explanation:
x = -b+/- (sq) b^2 - 4ac.
Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0
S if you use your equation : 3x^2 = 20 - 7x
First you have to move everything to one side.
So it'll look like this:
3x^2 = 20 - 7x
-20 -20
3x^2 - 20 = -7x
+7x +7x
3x^2 - 20 + 7x = 0
don't forget that... Ax^2 +Bx+ C= 0
3 = A
7 = B
-20 = C
