Maths help please ax²+bx+c = 0 with a not equal on zero?
OK





ax^2 + bx + c = 0 is the standard formula. But you need to know if we have something else where it is NOT = 0 such as this:





ax^2 + bx + c = y ; where y is not 0.





You have several ways to solve this. First, subtract y from both sides to make it 0:





a^2 + bx + c -y = 0. If c-y make the trinomial factorable, you are in luck. Factor and solve.





If c-y does not make the trinomial factorable, use the quadractic formula (remembering to use c-y as c)





-b +-sqrt(b^2 - 4(a)(c)) / 2a





Hope that information is helpful.
