Question

(4y^a - 6x^b)(4y^a + 6x^b)

Answer 1

same thing

Answer 2

wow thanks

Answer 3

what do you actually need to do... as its not an equation so can't subtract 6x from both sides

Answer 4

now im confused.. i needed to foil this..

Answer 5

yes foild this first. There is no equation so you cant do ^^^^ all that. Do you know how to foil it?

Answer 6

its is simply the difference of 2 squares... if you are exanding

(a + b)(a - b ) = a^2 - b^2

Answer 7

uhhm i know how to set it up.. like first outter inner last but i dunno wtf 4ya times 4ya would come out to be..

Answer 8

so you will have

\[(4y^a)^2 - (6x^b)^2 \]

that you need to simplify

Answer 9

sooo 16y^(a2)-36x^(b2) ??

Answer 10

you dont need to actually, use what campell said

example:

(4x^2 -16b^2) = ((2x)^2 - (4b)^2) = (2x-4)(2x+4)

Answer 11

thanks erryybody!

Answer 12

correct

Answer 13

\[16y^{2a} - 36x^{2b}\]
