ok thanks. I have to make up a equation for my class would -3x^2+30x-15=0 be in standard form? I cant never made up one and it work out right.

anonymous · Answer

yes, it certainly would be.

anonymous · Answer

one way to think of one which "works out right" is to come up with the answers then work backwards to form the equation

x = 2, x = 3:

(x - 2)(x - 3) = 0

then expand the left hand side:

x^2 - 5x + 6 = 0
