Question

plz tell this questions answer I need to confirm my answer​

Answer 1

Answer:

3a(a+b+c)-2b(a+b+c) from 4c(-a+b+c)

4c(-a+b+c)- 3a(a+b+c)-2b(a+b+c)

-4ac+4bc+4c²-3a²-3ab -3ac-2ab-2ab-2bc

-4ac-3ac+4bc-2bc+4c²-3a²-3ab-2ab-2ab

-7ac +2bc +4c² +3a² -7ab

3a²+4c²-7ab-7ac+2bc

Answer 2

Answer:

Step-by-step explanation:

Let x=3a(a+b-c)-2b(a-b+c)

x=3a²+3ab-3ca

also let y=4c(-a+b+c)

y=-4ac+4bc+4c²

We want to subtract x from y

=y-x

=(-4ac+4bc+4c²)-(3a²+3ab-3ca)

= -4ac+4bc+4c²-3a²-3ab+3ca

=-3a²+4c²-4ac+4bc-3ab+3ca
