Question

Factorise m(2a-b)-2n(b-2a)

Answer 1

Step-by-step explanation:

m(2a - b) - 2n(b - 2a)

= m(2a - b) - (-2n)(2a - b)

= m(2a - b) + 2n(2a - b)

= (m + 2n)(2a - b)

mark as brainliest.

Answer 2

Step-by-step explanation:

$\sf m(2a - b) - 2n(b-2a)$

$\implies \sf 2am + 4an - bm - 2bn$

Taking out the common factors will give,

$\implies \sf (m+2n)(2a-b)$

Hope it helps.
