Be careful with the +/- with the answer.

A general rule for the GRE is the following:

- If the radical appears in the question, only consider the positive root

- If you perform a square root during algebra, say to turn \(x^2\) to \(x\), then you should consider +/-

Since the former is true in this case, we only consider the positive root, so the answer is C.

here quant B is the \((a+b)^2\) expansion of quant A

i.e, \((3x^2 +5)^2\)=\(9x^4+30x^2+25\)

so \sqrt{quant B} =quant A

option C is correct
