i need help with a couple of problems(adsbygoogle = window.adsbygoogle || []).push({});

1.

(x+3)^2/3=3

I don't even know were to start

2.1 - 1 = 3

- ---

x x+1

LCD is (x)(x+1)

1(x)(x+1) - 1(x)(x+1) = 3(x)(x+1)

--------- --------- ---------

x(x+1) (x)x+1 (x)(x+1)

1x+1 - 1x = 3x^2 + 3x

3x^2 + 3x + 1 = 0

3^2 - 4(3)(1)

that is all i have and i don't think it is right because the answer should be

-3 + or - the squ. root of 11
