So you need to turn 5x^2 -3x -9 into 2x - 3.
Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).
Then -3x needs to become 2x by adding 5x (+5x).
Finally -9 needs to become -3 by adding 6 (+6).
Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6

Answer:
f(11) = 78
Step-by-step explanation:
f(x) = 7(x-1) + 8
f(11)
x = 11
f(11) = 7(11-1) + 8
=7(10) + 8
= 70 + 8
= 78
