Im not in high School, but I am studying for my GMAT and need some help with some stuff that I havnt done in years.
What are the formulas for finding the intercepts of a quadratic equation.
I think negetive b plus minus the square root of 4ac divided by 2a is this correct? which intercept does this give you? Whats the formula for finding the other intercept?
How do you solve a problem where you are given the intercepts and asked to choose which equation?
What equation has te intercepts of (-1,-5)
No graphing calculators allowed or else this would be easy.
