Quadratic formula?

Answer 3

Not sure. Isn't it trinomial

Answer 4

Nevermind

Answer 5

Answer 6

Ignore the y first, then factor it like normal and add a y at the back of the term with no x's after factoring

Answer 7

Example
x^2 - 2xy + y^2
Ignore the y's.
x^2 - 2x + 1
Factor it
(x - 1)^2
Add the y to the term with no x's.
(x - y)^2

But y's to the second power to

Answer 9

Yes, it is and my method will work for that

Answer 11

No

Answer 12

It's (x - 12)(x + 1) , somehow you got the signs mixed up

Answer 13

Now add the y's to the constant number in each binomials

Answer 14

Umm... so (x-12y)(x+y)?

Answer 15

Yes
