Question

9 into 2 a minus b whole square minus 4 into 2 a minus b whole minus 13​

Answer 1

Given:

9[2a - b]² - 4[2a - b] - 13

To find:

Factorize

Solution:

Let's assume [2a - b] as "x" and find the factors of the given problem.

Therefore, we have

9x² - 4x - 13

= 9x² - (13 - 9)x - 13

= 9x² - 13x + 9x - 13

= x(9x - 13) + 1(9x - 13)

= (9x - 13)(x + 1)

Now, let substitute back x = (2a - b)

= [9(2a - b) - 13] [(2a - b) + 1]

= [ 18a - 9b - 13 ] [ 2a - b + 1 ]

Thus, the final answer is (18a - 9b - 13)(2a - b + 1).
