No it can't be factorised
For and quadratic equation ax^2 + bx + c = 0
If b^2 – 4ac is equal to 0 or a perfect square then it can be factorised for real roots
If b^2 – 4ac is greater than 0 but not a perfect square then it can't be factorised but will have real roots.
If b^2 – 4ac is less than 0 then the equation will have complex roots.
