F(x) = 2x + 3
f(a) = 2a + 3
when f(a) = 11
11 = 2a + 3
therefore 2a = 8
and a = 4
Answer:
2x2−6x−4
Step-by-step explanation:
Let's simplify step-by-step.
5x^2+2x−11−(3x^2+8x−7)
Distribute the Negative Sign:
=5x^2+2x−11+−1(3x^2+8x−7)
=5x^2+2x+−11+−1(3x^2)+−1(8x)+(−1)(−7)
=5x^2+2x+−11+−3x^2+−8x+7
Combine Like Terms:
=5x^2+2x+−11+−3x^2+−8x+7
=(5x^2+−3x^2)+(2x+−8x)+(−11+7)
=2x^2+−6x+−4
