Look at the National 4 factorising section before continuing. When a question asks you to 'solve' a quadratic equation, this means that you are to find the roots of the quadratic. In other words ...

When asked to solve a quadratic equation, we are really finding the roots – where the parabola cuts the x-axis, therefore when we have the graph drawn, it is very easy to do this. Looking at the ...

Everyone learns (and some readers maybe still remember) the quadratic formula. It’s a pillar of algebra and allows you to solve equations like Ax 2 +Bx+C=0. But just because you’ve used it ...

Solve the quadratic equation x² - 5x - 14 = 0 using factorization and formula. Get roots x = 7 and x = -2. Use the quadratic formula x = (-b ± √(b² - 4ac)) / 2a. Find speed of train traveling ...

The standard equation for a parabola is: You may recognize this as a quadratic function; a parabola is a graphic depiction of a quadratic function. In the equation above, a, b and c are constants ...
