Question

y=-x^2-2x+3

Answer 1

What do you want us to do? Factor it? Solve for x?

Answer 2

okay so if you are trying to factor follow me.

Since the last sign is a plus sign and the first is negative, we know that both binomials will be negative.
-------------

What helps me solve this is i think of it like this:
What adds or subtracts to the coefficient (-2x) and multiplies to the constant (3)?

So if you factor out

(x - 3) (x - 1), you will get a un-reduced

x^2 + x - 3x + 3 , then combine like terms

x^2 - 2x + 3.

So therefor your answer is (if you are factoring)
(x - 3) (x - 1)
or
(x - 1) (x - 3)

Answer 3

Hope i helped!!

Answer 4

i thnk he want to know Y and x

Answer 5

This is a quadratic equation. I can only assume that he/she needs to factor.
If not then use substitution. to determine x or y.
