Answer 4

@isaidavila can you help me with this one??

Answer 5

Hint:

\(\bf a^2 + 2ab + b^2 = (a+b)^2\\a^2-2ab+b^2 = (a-b)^2\)

So we have 3x in place of 2ab, and we know that a = x.

So we have:

3x = 2xb
3 = 2b

what is 'b'?

and then whatever you get, we need to square that because we need to find \(\bf b^2\)

Answer 6

-3

Answer 7

What did you find as "-3"

Hint:

3 = 2b

Solve for b, and then square it to find \(\bf b^2\)

Answer 8

-3/2

Answer 9

is it right?? @AbdullahM

Answer 10

hint: \(\bf\Large\left(\frac{a}{b}\right)^2 =\frac{a^2}{b^2}\)

Answer 11

9/4 d.
