The H C F of a2bx ab2x and a2b - b2 is - JAMB Mathematics 1990 Question
The H.C.F. of a2bx + ab2x and a2b - b2 is
A
b
B
a + b
C
b(a \(\div\) b)
D
abx(a2 - b2)
correct option: b
a2bx + ab2x; a2b - b2
abx(a + b); b(a2 - b2)
b(a + b)(a + b)
∴ H.C.F. = (a + b)
abx(a + b); b(a2 - b2)
b(a + b)(a + b)
∴ H.C.F. = (a + b)
