Question

(x-2)(3x^2-6x+12) multiplying polynomials,,can anyone multiply and simplify?

Answer 1

Use the distributive property. Distribute the x across all the terms in the second quantity and then distribute the -2 across. Combine like terms and you are done!

Answer 2

thanks!

Answer 3

(x+4) and (x-1)

Why? Well, let us multiply them to see:

(x+4)(x-1) = x(x-1) + 4(x-1)
= x2 - x + 4x - 4
= x2 + 3x - 4
Multiplying (x+4)(x-1) together is called Expanding.

In fact, Expanding and Factoring are opposites:



Expanding is easy, but Factoring can often be tricky


It can be like trying to find out what ingredients went into a cake to make it so delicious.

It is sometimes not obvious at all!

So let us try an example where we don't know the factors yet:

Answer 4

Not factoring.

Answer 5

who?

Answer 6

I think he meant to type that in a different question?

Answer 7

yea prob,that's not the same question i'll try to work it out
