The answer is B. 

Do you need the explanation?


<span> (3x^3 - 7x^2 + 12) - (3x^3 + 6x^2 + 10x)
</span>First, remove parentheses


3x^3 - 7x^2 + 12 - 3x^3 -6x^2 -10x
eliminate the opposites 

then collect the like terms 
13x^2 +12 - 10x

and finally, use the commutative property to reorder the terms, and you'll get 
-13x^2-10x+12

Can you tell me how to factorise 6b+24bc
Kamila [148]
When we factorise an expression, we are looking for simple factors that multiply to get the original expression. Usually it is very natural to factorise something like a quadratic in x. For example:

x^2 + 3x + 2 = (x+1)(x+2)

But there are other situations where factorisation can be applied. Take this quadratic:

x^2 - 9x = x(x-9)

This second example is closer to the question in hand. Just like x was a common factor to both x^2 and -9x, we are looking for a common factor to both 6b and 24bc. The common factor is 6b.

Hence 6b + 24bc = 6b(1 + 4c).

I hope this helps you :)
