The given equation reduces to:
x²+9x+4=0
which cannot be factored by inspection since the factors are not rational.
You can use the quadratic formula or completing the squares to find the irrational factors, namely:
(x+4.5+√65/2)(x+4.5-√65/2)
x²+9x+4=0
which cannot be factored by inspection since the factors are not rational.
