Kudos for R.A.E
\((5+a)(3+a) = a^2 + 8a + 15\)
Comparing both quantities
QTY A = \(a^2 + 8a + 15\)
QTY B = \(a^2 + 2a + 15\)
\({a^2 + 15}\) is common in both the quantities and so we can cancel them .
Now QTY A = \(8a\)
QTY B = \(2a\)
But it cannot be proved which QTY will be greater, because if
a is positive then QTY A > QTY B
if a is negative then QTY A < QTY B
therefore option D
