Question

write the equation in standard form,
y^2 +4x-6y+5=0

jdoe0001 · Answer

hmm do you know what a "perfect square trinomial" is?

anonymous · Answer

1) (y-5)(y-1) = 0 
2) (x+7)^2 = 0 
3) 5(x^2 - 25) = 0 
(x-5)(x+5) = 0 
x = 5 or x = -5

yes sortof but its been a while since then

anonymous · Answer

Whenever you multiply a binomial by itself twice, the resulting tri-nominal is called a perfect square tri-nominal

An Example:
(x + 1) × (x + 1) = x2 + x + x + 1 = x2 + 2x + 1 and x2 + 2x + 1 is a perfect square tri-nominal

i cant go to links my mom has it set up so i have to email her for permission, im trying to get the equation in standard form so i can get the vertex, focus, and the equation of the directrix of the porabola

anonymous · Answer

at least i think its a parabola

jdoe0001 · Answer

ahemm     well... to do that you'd need to check your what a perfect square trinomial is first

anonymous · Answer

ok i looked at it

jdoe0001 · Answer

..... so...do you recall what it's?

jdoe0001 · Answer

hmmm that'd be the difference of cubes

anonymous · Answer

ok then i have no idea :'(
