Poly. And Factoring Questiosn I have...

Bah help me quick someone please...
Determine wheter expression A is equivalent to Expression B. If not, change exp b to make it quivalent...
a b
2X^2-7X-15 (2X-3)(X-5)
2X^2-11X+12 (2X-4)(2X-3)
4X^2+8X-12 4(X-1)(X+3)
I don't get how you find if its equiv well i do but i don't know how you find the correct expression

Hi!

To find the correct expression, I guess all you need to do is to factorize expression A. Once you have done so, you can see where the mistake in expression B lies and you can change it accordingly.

Hope this information helps!

I think it's easier to multiply B and see if it is the same as A!
