===Perfect Square Trinomials===

Perfect square trinomials are of the form <math>a^2+2ab+c^2</math> or <math>a^2-2ab+c^2</math><br />

<math>a^2+2ab+cb^2=(a+cb)^2</math> and<br />

<math>a^2-2ab+cb^2=(a-cb)^2</math><br /><br />

'''For example:'''<br />

<math>4h^2-20h+25=(2h)^2-2(2h)(5)+(5)^2=(2h-5)^2</math><br />
