Question

(a + b) ( a*2 ─ ab + b*2) is the expansion of
a) a*3 + b*3
b ) a*2 + b*2
c) (a ─ b)*3
d) None of these

Answer 1

Answer:

(a + b) ( a*2 ─ ab + b*2) is the expansion of

(a + b) ( a*2 ─ ab + b*2) is the expansion ofa) a*3 + b*3

(a + b) ( a*2 ─ ab + b*2) is the expansion ofa) a*3 + b*3b ) a*2 + b*2

(a + b) ( a*2 ─ ab + b*2) is the expansion ofa) a*3 + b*3b ) a*2 + b*2c) (a ─ b)*3

(a + b) ( a*2 ─ ab + b*2) is the expansion ofa) a*3 + b*3b ) a*2 + b*2c) (a ─ b)*3d) None of these

answer :

a)
