Answer:

Ok, here goes: f(3) means take f(x) and plug in 3 wherever we see x. So

f(3) = 12*39 + 3 = 236196 + 3

f(3) = 236199

Likewise, f(-3) means take f(x) and plug in (-3) wherever we see x. So

f(-3) = 12*(-3)9 + (-3) = -236196 - 3

f(-3) = -236199

Putting those two things together, we get

f(3) + f(-3) = 236199 - 236199 = 0

Square the binomial<br>(2x - 3)²

n200080 [17]

Step-by-step explanation:

Change it into this

(2x-3)(2x-3)

Then multiply the insides and outsides and add them

(2x*2x) + (2x* -3) + (-3*2x) + (-3*-3)

Simplify

4x^2 - 6x -6x + 9

Simplify again

4x^2 - 12x + 9
