Solve the equation y^2+3y+2 = 0 how is the equation y^2+3yx+2x^2 related
8 answers
how are they differnt
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?
(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?
How did you solve y^2 + 3xy + 2x^2 = 0? Im confused at the one.
Huh? I just factored it. The solution is two straight lines; it is a degenerate hyperbola.
I mean in Quadratic forms I don't even know what is a degenrate hyperbola.
This is on my test tommrow.
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.
