Question

Can someone tell me how to multiply these together. For some reason i forgot

6(x+a)(x-a) + 6(x-a)(x-1)

The book says 12x^2-12x
I have no idea how they got that.
Please explain how the answer was obtained. Do you distribute the 6 to both binomials? and then combine? But that makes no sense

Answer 1

any ideas?

Answer 2

first factor out the binomials then multiply the 6 out

Answer 3

so u foil the binomials into one trem then distribute the 6

Answer 4

yeah basically

Answer 5

that doesnt work

Answer 6

are you sure that's the correct answer? you might want to look back at the answer there should be an a in it or else it doesnt work..

Answer 7

thats what the book says there is a picture

Answer 8

(x-a)(x+a) =x^2 - a^2
(x-a)(x-1) = x^2 +a -x -ax

Answer 9

would u care to explain? that obviously is not a foil
