Factorising quadratics - (easy)

(The third of three ways to solve (find the roots) of quadratics)

We know factors are found using ladders, and we know quadratics have an $x^2$ term.

To factor a general quadratic formula as

$x^2+bx+c=0$

Use ladders as follows:

Remember

This method follows along the lines of the ladder factorising method

NOTE:

Find factors of $c$ that add to give $b$ .
