[tex] x = \frac{b}{2a} [/tex]
for example let's say we have 2x²+4x+3
Step-by-step explanation:
4 is the co-efficient of x therefore you substitute 4 in terms of b. 2 is the co-efficient of x² therefore you substitute 2 in terms of a.
[tex] x = \frac{4}{2(2)} [/tex]you will find your x value then you will substitute x from the original formula to get your y value.
