Question

(3x-4y)^2

Answer 1

Use FOIL for distribution. First, Outside, Inside, Last

Answer 2

(3x-4y)(3x-4y).
3x*3x
3x*-4y
-4y*3x
-4y*-4y

Answer 3

i have to multiply the polynomial

Answer 4

yes. so 3x*-4y would be -12xy

Answer 5

3x*3x is 9x^2 and -4y*-4y is 16y^2.

Answer 6

snce you have 3x*-4y twice you take the answer to that (-12xy) and put them together (-24xy)

Answer 7

no i dont have twice

Answer 8

your then take all those solutions and put them together. 9x^2-24xy+16y^2

Answer 9

i dont have (3x-4y)^2 twice

Answer 10

When squaring a polynomial you are going to get a long answer. Using FOIL makes sure that you square the whole thing. (3x-4y)^2 can also be written as (3x-4y)(3x-4y)

Answer 11

so whats the answer

Answer 12

9x^2-24xy+16y^2
