(5x + 7)(2x - 3)

you add the 5x from the first term with the 7 from the second term, and multiply it by (2x-3) so it will look like:

(5x+7)(2x-3)

It's :

(5 x + 7)(2 x - 3).

This is found as follows ---

Since (2 x - 3) is common to both terms, you can simply COMBINE the two separate factors of that common expression (2 x - 3), that is both (+) 5 x and + 7, into another factor, namely (5 x + 7).

That then yields:

(5 x + 7)(2 x - 3)

as the final factorization.

5x(2x-3)+7(2x-3)
Use distributive property. Distribute the term outside the parentheses to those inside:
10x^2 - 15x + 14x -21
combine similar terms
10x^2 - x - 21
(5x + 7) (2x - 3)

Qn: 5x(2x-3)+7(2x-3)

The common factor in this qn is (2x-3)
If we take out (2x-3), we are left with
(2x-3)(5x+7)

instead of multiplying (2x-3) by 5x and then separately by 7 as is written originally, just multiply 5x and 7 in one paranthesis, as (5x+7)(2x-3)

you can tell that their the same because (5x+7)(2x-3) equals 10xsquared +4x-21, which is the same thing you get when you multiply 5x(2x-3)+7(2x-3)

take out a (2x-3)

(2x-3) (5x+7)
