Question

Simplify. b (−3)∙(2a+b)−4(b−a) Plz and Thanks

Answer 1

-6ab-3b^2-4b+4a

Explanation:

Split the problem in half: b (−3)∙(2a+b) −4(b−a)

Solve the first half:

b(-3) = -3b

-3b x -2a = -6ab

-3b x b = -3b^2

First Half: -6a-3b

Solve the second half:

-4 x b = -4b

-4 x -a = 4a

Second Half: -4b+4a

Put it all back together: -6ab-3b^2-4b+4a
