Answer:
X=-1 or X=3
Step-by-step explanation:
<u>STEP1</u>
Factor left side of equation
X^2-2X-3=0
(X+1)(X-3)=0
<u>STEP2</u><u> </u>
Set each factor to 0
X+1=0
X-3=0
<u>STEP3</u>
Answer
X=-1
Or
X=3
Please confirm the question is x = (-7x^2 - 1) / (x + 4)
if that is the case, then
x * (x + 4) = -7x^2 - 1
x^2 + 4x = -7x^2 -1
8x^2 + 4x + 1 = 0
which does not have any real solution
Edit - much easier question to evaluate the expression (x^2 -1) / (x + 4) when x=-7
(-7^2 - 1) / (-7 + 4)
= (49 -1 ) / -3
= 48 / -3
= -16
