Question

Solve for x.

4(x + 3)^2 + 5 = 10

Answer 1

I need a bit help solving this problem. I'm afraid I forgot Algebra and it's been awhile since I have done it. I would appreciate some help. Thanks! :)

Answer 2

For solving this do you know the conception of : Quadratic Equations ?

Answer 3

Ok so this is where I got so far:

4(x + 3)^2 + 5 = 10
-5 -5
4(x + 3)^2= 5

This is where I forgot how to do it..

Answer 4

K got it. Thanks :)

Answer 5

\[4(x+3)^2+5=10\\\\ (x+3)^2= \frac{10}{4}\\ x+3 = \pm \sqrt {\frac{10}{ 4 }}\\ x+3 =\frac{ \pm \sqrt{5} }{ 2 }\\\\ x = -3 \pm\frac{ \sqrt{5} }{ 2 }\\\\ x = -3+\frac{\sqrt{5} }{ 2 }\ \ \ and \ \ \ \ x = -3-\frac{\sqrt{5} }{ 2 }\\ \]
