Find the expression x = -7 x2 -1 / x+4

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

Answer is either b or c
