Question

divide 7ab(a²-b²) by a(a+b)​

Answer 1

Answer:

7b(a-b)

Step-by-step explanation:

7ab(a²-b²) (a is cancelled)

————— = 7b(a+b)(a-b)

a(a+b) ———— (a+b) is cancelled nr dr

(a+b)

=7b(a-b)

Answer 2

Given: $7ab(a^2-b^2) \ by\ a(a+b)$

We have to divide$7ab(a^2-b^2) \ by\ a(a+b)$.

As we know that the division is one of the basic operations of arithmetic, the ways that numbers are combined to make new numbers.

The division is denoted by a sign$(\div)$.

We are solving in the following way:

We have,

$7ab(a^2-b^2) \ by\ a(a+b)$

Solving the above equation further we get,

$=>7ab\times a^2-7ab\times b^2\div a\times a+a\times b\\=>7a^3b-7ab^3\div a^2+ab\\\\=>\frac{7a^3b-7ab^3}{a^2+ab}$

Hence, the solution of the above equation is$\frac{7a^3b-7ab^3}{a^2+ab}$.
