Cannot be factored

a factor is something of the form (x-a) where a is a root of the equation
so first find the roots using the quadratic equation
.you will get your two roots a and b from that eqn
Then simply make the factors as above. SO you will have (x-a) and (x-b) being your two factors
THen remember a quadratic is the product of its two factors. so your final answer will be (x-a)*(x-b)

To start factoring this, you would multiply 5 * -1 and get -5. Then you need to find factors of -5 that add to 1. Factors of -5 are: 1, -5, -1, 5. None of those combinations add up to 1. Therefore, this expression cannot be factored.
