Question #054f6

Answer 1

You cannot factor this.

Explanation:

We are actually unable to factor this equation (unless you use the quadratic formula). This is because `65=13\cdot5`, so there is no way to create a coefficient of `4` for the `x` term (`13-5=8,-13+5=-8`)

However, let's just find the roots.

Using the quadratic formula,

`x=(-4\pmsqrt(4^2-(4)(1)(-65)))/2=(-4\pmsqrt(16+260))/2=(-4\pmsqrt(276))/2=(-4\pm2sqrt(69))/2=-2pmsqrt(69)`
