Question

divide: 7ab(a^2-b^2) by a(a+b)​

Answer 1

Answer:

We divide the given polynomial 5a

3

b−7ab

3

by the monomial ab as shown below:

ab

5a

3

b−7ab

3

=

ab

5a

3

b

−

ab

7ab

3

=

ab

5a

3

b

−

ab

7ab

3

=

a×b

5×a×a×a×b

−

a×b

7×a×b×b×b

=5a

2

−7b

2

Hence,

ab

5a

3

b−7ab

3

=5a

2

−7b

.

Answer 2

Step-by-step explanation:

$\frac{7ab( {a}^{2} - {b}^{2}) }{a(a + \: b)} \\ we \: can \: write \: ( {a}^{2} - {b}^{2}) = (a + b) (a - b) \\ \frac{7ab(a + b)(a - b)}{a(a + b)} \\ 7b(a - b)$

i hope you can understand
