Question

Determine the factor of x^2-12x-20

Answer 1

there is no GCF and you can’t use the square root method so you must use the quadratic formlula

Answer 2

The roots are: (12 +
`√(224)`)/2 and (12 -
`√(224)`)/2

Explanation:

We can solve this with the quadratic formula! Plugging it all in, we get (12 +/-
`√(144+80)`)/2 This simplifies to (12 +/-
`√(224)`)/2. So the roots of our equation are (12 +
`√(224)`)/2 and (12 -
`√(224)`)/2.
