Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Write Equation In Standard Form: $\bold{ax^2+bx+c}$

$\bold{x^2-3x-28}$

[ Step Two ] Break Expression Into Groups

$\bold{\left(x^2+4x\right)+\left(-7x-28\right)}$

[ Step Three ] Factor

Factor Out $\bold{x}$ From $\bold{x^2+4x: \ x\left(x+4\right)}$

Factor Out $\bold{-7}$ From $\bold{-7x-28: \ -7\left(x+4\right)}$

[ Step Four ] Rewrite Equation

$\bold{x\left(x+4\right)-7\left(x+4\right)}$

[ Step Five ] Factor Out Common Term $\bold{x+4}$

$\bold{\left(x+4\right)\left(x-7\right)}$
