Question

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

Answer 1

Answer:

4c2-3a2-2b2-ab+6bc-7ac

Step-by-step explanation:

4c(−a+b+c)−[3a(a+b+c)−2b(a−b+c)]

4c(−a+b+c)−[3a 2 +3ab+3ac−2ab+2b 2−2bc]

4c(−a+b+c)−[3a 2 +2b 2+ab+3ac−2bc]

−4ac+4bc+4c 2 −3a 2−2b 2 −ab−3ac+2bc

4c2-3a2-2b2-ab+6bc-7ac
