Question is -

If f(x) = x(x + 1) and g(y) = y( y²-1) , Then evaluate the HCF of
f(b) - f(a) and g(b) - g(a) :
A.) a + b
B.) b - a
C.) b² + a²
D.) a² + b² + ab


This question needs a perfect answer ; and it doesn't support lazy ones ! Take care

Answer 1

f(b)=b(b+1)=b2+b
f(a)=a(a+1)=a2+a

f(b)-f(a)=b2+b-a2-a


g(b)=b(b2-1)=b3-b
g(a)=a(a2-1)=a3-a

g(b)-g(a)=b3-b-a3+a

HCF:-
Option B {b-a}
I think so....

Answer 2

so the answer is option B (b-a)
