3) (4x)(6x+6) = 24x^2 + 4x
4) ((6)+4)(5(6)) = 300
5) 4x(x+1)= 4x^2+4x
6) (-x-3)(-5x+10) = 5x^2+5x-30
7) (2(4)+3)(5(4)-2) = 198

The answer would be p= -2

To check it:
-2(5(-2) - 3) = 26
-2(-10-3) = 26
-2(-13) = 26
26 = 26

F(x) = -2x²-2x+10, find f(2)

beks73 [17]

Answer:

f(2) = -2

Step-by-step explanation:

Substitute 2 everywhere you see an x so f(2) = -2( $2^{2}$ ) - 2(2) + 10 so

f(2) = -2(4) - 4 + 10, so f(2) = -8-4+10, f(2) = -12+10, f(2) = -2
