a3 + 3ab(a + b) + b3 = _____
a) 3(a + b)3
b) (3a + 3b)3
c) (a + b)3
d) 3(a + b)3
Explanation:
(a +b)3 = a3 + b3 + 3a2b + 3ab2
which can be written as:
a3 + 3ab(a + b) + b3
if a2 – 2ab + b2 = 36 and a2–3ab+b2 = 22 the ab = ?
a) 12
b) 14
c) 8
d) 6
Explanation: Let a2 – 2ab + b2 = 36 --(i)
and a2 – 3ab + b2 = 22 ------(ii)
Subtract Eq (ii) from Eq (i) we get
ab = 14
