Question

If h(x)=x^2+x and g(y)=x^3-x then HCF of h(b)-h(a) and g(b)-g(a) is:
1)a+b
2)a^2+b^2
3)b-a
4)b^2+ab+a^2

Answer 1

Answer:

your answer is option 2

Answer 2

we know

2(ab + bc + ca) = (a + b + c)2 – (a? + b + c)

= 2(ab + bc + ca) 12 - 2 = -1

> ab + bc + ca =

given

a + b3 + c = 3 = a + b3 + c – 3abc + 3abc = 3 > (a + b+ c) (a? + b + c? – ab – bc – ca) + 3abc = 3 = (a + b + c)(a + b + c - (ab + bc + ca) + 3abc = 3

2 option is the answer
