Question

1. x²-ab+(a-b)x
2. 2ab -3cd - 3bc + 2ad​

Answer 1

Answer:

1. Factorizing

$x { }^{2} -( a + b)x + ab$

$= x {}^{2} - ax - bx + ab$

$= x(x - a) - b(x - a)$

$= (x - a)(x - b)$

2 .

$2ab - 3cd - 3bc + 2ad$

➩ Do the grouping 2ab+2ad−3cd - 3bc =(2ab+2ad)+(−3cd – 3 bc ), and factor out 2a in the first and −3c in the second group.

$2a(b - d) + 3c(b - d)$

Factor out common term b – d by using distributive property.

$(b + d)(2a + 3c)$

this much only I know ..

hope this helps u :)
