Question

Solve (x + 3)^2 + (x + 3) – 2 = 0.
Let u = x+3
Rewrite the equation in terms of u.

A. u^2 + u – 2 = 0

B. (u^2 + 9) + u – 2 = 0

C. u^2 + u + 1 = 0

Answer 1

Answer:

The answer is the option A

$u^{2}+u-2=0$

Step-by-step explanation:

we have

$(x+3)^{2}+(x+3)-2=0$

Let

$u=(x+3)$

Substitute

$(u)^{2}+(u)-2=0$

Answer 2

Step-by-step explanation:

. Answer is B.
