Question

3b-3c          4c^2 --------- * ----------- c             b^2 - c^2

Answer 1

(3b - 3c)/c·(4c²)/(b² - c²) = 12c²(b - c)/c(b - c)(b + c) = 12c/(b + c) 

Answer 2

3(b-c)/c *4c²/[(b-c)(b+c)=12c/(b+c)

Answer 3

To simplify the expression, let's break it down step by step:

3b - 3c 4c^2

c b^2 - c^2

First, let's simplify the numerator: 3b - 3c = 3(b - c)

Now, let's simplify the denominator: b^2 - c^2 = (b + c)(b - c)

Now, we can rewrite the expression: (3(b - c))/(4c^2) * (c)/((b + c)(b - c))

Next, let's simplify further: 3/(4c) * 1/(b + c)

Now, we can combine the fractions: 3/(4c(b + c))

Therefore, the simplified form of the expression 3b-3c * 4c^2 / c(b^2 - c^2) is 3/(4c(b + c)).
