I'm struggling with quadratic equations
Quadratic equations can be tricky, to begin with, but once you get the hang of them they can become one of the best maths tools on offer to you. All quadratic equations with real roots can be solved with the quadratic formula. The quadratic formula is as follows: x=(-b±sqrt(b2 -4ac))/2a.
a is representative of the coefficient of the x2 - that is , the number before the x2 , b is the number before the x and c the final value at the end of your equation.
