Answer:

(We already know that: x -1/x-1 = 1 and x + 1/x + 1 = 1 there is no need of keeping them)

(x-1/x-1) x+5/x+1 -x-2/x-1(x+1/x+1)

= x + 5/x + 1 - x - 2/x - 1

= x²/x + 5/x + x/x - x²/x - 2/x - x/x

= x² + 5 + x - x² - 2 - x

= 5 -2

= 3

Answer:

$f(-1) = -12$

Step-by-step explanation:

<u>Step 1: Set x to -1 and solve</u>

<u /> $f(x) = -3x^2+2x-7$

$f(-1) = -3(-1)^2+2(-1) - 7$

$f(-1) = -3(1) - 2 - 7$

$f(-1) = -3 - 2 - 7$

$f(-1) = -12$

Answer: $f(-1) = -12$
