Question

Solve the equation y^2+3y+2 = 0 how is the equation y^2+3yx+2x^2 related

Answer 1

how are they differnt

Answer 2

y^2 + 3y + 2 = 0
(y+1)(y+2) = 0
y = -2, -1

y^2 + 3xy + 2x^2 = 0
(y+x)(y+2x) = 0
y = -x, y = -2x

so, what do you think?

Answer 3

How did you solve y^2 + 3xy + 2x^2 = 0? Im confused at the one.

Answer 4

Huh? I just factored it. The solution is two straight lines; it is a degenerate hyperbola.

Answer 5

I mean in Quadratic forms I don't even know what is a degenrate hyperbola.

Answer 6

This is on my test tommrow.

Answer 7

well, a quadratic form as all terms of the 2nd degree. So, the first equation is not even a quadratic form. It is just a quadratic equation.

There are lots of articles and videos available online (google is your friend), so whatever level of study you need is surely accessible there. First place to look -- your class textbook and your other homework assignments. You gotta assume that nothing will be asked on the test which you have not covered in class.

Answer 8

Alright I understood how to do it, i got Confusued cause of the xy
