Question

can someone please review my answer? :) medal and fan

Answer 1

\[(3x-11)^{2}+(\sqrt{4x)^{2}}\]

Answer 2

well i simplified that but i am confused on what happens to the 4x part, does it become 4x simply or 4x^2 ?

Answer 3

it becomes 4x

\[(\sqrt{4x})^2 = 4x\]

and you need to distribute the 1st part

\[(3x - 11)^2 = 9x^2 - 66x + 121 \]

then just collect the like terms
