Question

Factorize: 6(a+b)^2 - 19(a+b) -15​

Answer 1

Answer:

(3x-5)(2x-3) ans.

Step-by-step explanation:

Maybe there is sign mistake in your question

If your ques is this 6(a+b)² - 19(a+b) + 15

Then the solution will be

Let (a + b) be x

Therefore, 6x² - 19x + 15

=6x² - 9x - 10x + 15

=3x(2x - 3) - 5(2x - 3)

=(3x-5)(2x-3)ans.

Step-by-step explanation:

The difference of squares identity can be written:

A 2 − B 2 = ( A − B ) ( A + B )

We can use this with  A = a  and B = b − 3  as follows:

a 2 − b 2 + 6 b − 9= a 2 − ( b 2 − 6 b + 9 )

a 2 − b 2 + 6 b − 9 = a 2 − ( b − 3 ) 2

a 2 − b 2 + 6 b − 9  ( a − ( b − 3 ) ) ( a + ( b − 3 ) )

a 2 − b 2 + 6 b − 9 = ( a − b + 3 ) ( a + b − 3 )
