Which quadratic equation is equivalent to (x + 2)2 + 5(x + 2) – 6 = 0?
(u + 2)2 + 5(u + 2) – 6 = 0 where u = (x – 2)
u2 + 4 + 5u – 6 = 0 where u = (x – 2)
u2 + 5u – 6 = 0 where u = (x + 2)
u2 + u – 6 = 0 where u = (x + 2)

u2 + 5u – 6 = 0 where u = (x + 2

Choice C is correct answer.

Step-by-step explanation:

We have given a quadratic equation.

A quadratic equation is an equation of second degree.its standard form is ax²+bx+c = 0 where a,b and c are constants and x is variable.

(x+2)²+5(x+2)-6 = 0

We have to rewrite given quadratic equation by subtituting u = x+2.

Putting u = x+2 in given quadratic equation,we get

u²-5u-6 = 0 is also a quadratic equation which is equivalent to (x+2)²+5(x+2)-6 = 0 ,where u = (x+2).

Hence,Choice C is our answer.
