Question

multiply (x^2+8x+15)/(x-4)*(x^2-16)/(2x+6)

Answer 1

12

Answer 2

When you see this questions, you should think FACTOR. Factor all the terms as much as possible. There should be trinomial factoring and common factoring and difference of squares. Once you factor the terms, they should cancel out pretty easily!

Answer 3

its a multiple choice question:
a. x^4+8x-1/3x+2
b. (x+5)(x+4)/2
c. (x-5)(x+4)/2
d. x^4+8x^3-x/2x^3-24

Answer 4

I'd rather not give you the answer. Try factoring the terms. For example,

x^2+8x+15 = (x+5)(x+3)

Answer 5

can you help me factor the terms? i'm not sure I know how

Answer 6

you never learned how to factor?

Answer 7

yes, I did, but to be honest, i've forgotten how :/

Answer 8

above, @BluFoot gave you the answer for the first one, what you do is you start out by putting an x i ntwo set of parenthesis. Then you want to find two numbers that when added give you the 2nd term and that when multiplied give you the third term, thus 5+3=8(second term) 5x3=15(third term), its quite simple if you just take the time to apply yourself. Hope i helped :)

Answer 9

From above:
x^2+8x+15 = (x+5)(x+3)
(x^2-16) = ? (hint: difference of squares)
2x+6= ? (hint: common factoring)

Answer 10

I think I got it, i'll try to work it out on paper, thank you to the both of you :)
