Question

subtract 3a(a+b+c) from 4c(-a+b+c)​

Answer 1

Answer:

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

Answer 2

Answer:

-7ac+4bc+4c²-3a² -3ab

Step-by-step explanation:

Solution

3(a+b+c)

=(3a*a)+(3a*b)+(3a*c)

=3a²+3ab+3ac

4c(-a+b+c)

=(4*-a)+(4*b)+(4c*)

=-4ac+4bc+4c²

-4ac+4bc+4c²

3ac+ 0 + 0 +3a²+3ab

- - - - -
