Question

how do i factor an equation when its in y=?

Answer 1

Do you have a question or example?

Answer 2

yea y=x(squared)-x-6

Answer 3

So you have \(x^2-x-6\), now to solve this

Answer 4

not solve it i need to factor it

Answer 5

You need to find two numbers that when multiplied together, equal -6, BUT when you add these two numbers, you get -1

Answer 6

Yes, sorry I mean't factor.

Answer 7

y= doesn't really matter, it just means that y is a function of x or f(x). You just factor the right side. In the example you gave, this is how you would factor:\[y=x^2-x-6 \rightarrow y = (x-3)(x+2)\]Basically you have to find two numbers that multiply to -6 and add up to -1, those are -3 and +2 and that's how you would factor.

Answer 8

geesh, I was going to let faby try it out herself first instead of directly give her the answer :(

Answer 9

so the y= is basically the same as x= or f(x)

Answer 10

I didn't just give the answer. I gave an explanation -.-

Answer 11

Yeah.

Answer 12

When he sees where the answer comes from and where it goes, it will be easier for him/her to evaluate other similar questions...

Answer 13

w/e #YOLO!!!

Answer 14

well dont it have to be equal to zero in order to factor it? like -2x(squared)+10x-12=othen u would factor it to (-x+3)(2x-4)? i mean i know ho to factor im just confused because of the y=

Answer 15

or do i have to solve it using the quadratic formula? ughh ive been skipping school and didnt get to learn it so now im confused becaus ei dont usually see y= kind of equations just equations that are equal to zero

Answer 16

No no. You are getting the whole idea of factoring wrong. What you are talking about is finding the zeroes also known as x-intercepts. To find them, you let the whole polynomial equal zero, and then factor, and that way you can figure out at which x-values the function will be 0 at. Factoring can be done in other cases as well, not just when you're finding zeroes. You can factor to make an expression simpler and so on. But when you are finding zeroes, you just factor and let the whole thing equal and find which x's it's 0 at.
