Question

factor completely. 5x^2+53x+72

Answer 1

hint :
5 = 5 * 1
72 = 8 * 9
5 * 9 + 1 * 8 = 53
nah, continue it ..

Answer 2

So first we can establish that this is a quadratic equation which can be solved multiple ways:
- X-method
-Quadratic formula
-Completing the square

My method of chose is the quadratic formula just for the simplicity of things..
\[(-b \pm \sqrt{b^2-4ac})/2a\]
Which you then plug in your numbers..
And will get two answers, you will then check both answers to make sure they are correct.
