Question

3a(a+b+c)- 2b (a-b+c) from (-a+b+c)​

Answer 1

Answer:

3a²−ab−2b²+3ac+2bc

Step-by-step explanation:

3a(a−b+c)+2b(a−b+c)

=(3a+2b)(a−b+c)

=3a²- 3ab+3ac+2ab−2b²+2bc

=3a²−ab−2b²+3ac+2bc

Answer 2

Answer:

The answer is Add 3a(a - b + c) 2b (a - b + c)

Step-by-step explanation:

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

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

=3a2-3ab+3ac+2ab -2b2+2bc

=3a2-ab-2b2+3ac+2bc
