Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Eduqas.

Let's solve them together. Quadratic equations are polynomials that include an x², and teachers use them to teach students to find two solutions at once.

That formula can be used to solve standard form quadratic equations, where ax 2 + bx + c = 0. In September, Loh was brainstorming the mathematics behind quadratic equations when he struck upon a new, ...

Notice that the graph of the quadratic function is a parabola. This means it is a curve with a single bump. The graph is symmetric about a line called the axis of symmetry. The point where ... Solve ...

On a graph, for any parabola ... The first attempts to find a more general formula for solving quadratic equations may have been made by Greek philosophers Pythagoras (c. 500 BC) and Euclid ...

“If you graph it, ... This alternate method for solving quadratic equations uses the fact that parabolas are symmetrical. For example, in this parabola: y = x 2 – 4 x – 5 .
