Find and correct the errors in the following mathematical statements

Q7

$( 2x )^2 + 4 ( 2x ) + 7 = 2 x^2 + 8 x +7$

Our L.H.S. is
$(2x)^2 + 4(2x) + 7 = 4x^2 + 8x + 7$
R.H.S. $= 2x^2+8x+7$
It is clear  from the above that L.H.S. is not equal to R.H.S.
So, correct statement is
$(2x)^2 + 4(2x) + 7 = 4x^2 + 8x + 7$
