Question

I want answer of this question with steps and explanation

Answer 1

Answer- ab[(a^5) -10ab+3(a^2)]

Step-by-step explanation:

on multiplying both the equations -

(a^5) b-2(a^4 )b+3 (a^3)b       and

2(a^4)b +6(a^3)b -10a(b^2)

on adding we get  (a^5)b+9(a^3)b-10a(b^2)

and on simplification  ab[(a^5) -10ab+3(a^2)]
