${ \red{Let \: 2a-b} \orange= \red{x}}$

${ \orange\therefore \purple {x^2+2x-8}}$

${ \orange= \pink{x^2+4x-2x-8}}$

${ \orange= \blue{x(x+4)-2(x+4)}}$

Answer 2

Answer:

Let2a−b=x

${{ \orange\therefore \purple {x^2+2x-8}}∴x </p><p>2$

+2x−8

${ \orange= \pink{x^2+4x-2x-8}}=x </p><p>2$

+4x−2x−8

${ \orange= \blue{x(x+4)-2(x+4)}}=x(x+4)−2(x+4)$

${ \orange= \bold \red{ \fbox \green{(2a-b+4)(2a-b-2)}}}= (2a-b+4)(2a-b-2)$

${ \blue{[putting \: \: x} \orange= \red{2a-b]}}[puttingx=2a−b]$
