Step-by-step explanation:

We had to use middle term splitting method to factorise it :

In this , we have to find two number such that there sum is middle term and product is product of first and last term .

In this question , suitable numbers are (-5x) and 6x

Now , factorising :

x² + x - 30

=x²+6x - 5x -30

Taking common 'x' in first two terms and '5' in last two terms .

=x(x+6)-5(x+6)

Taking common (x+6) in whole .

=(x + 6)(x - 5)

Therefore, your answer comes (x + 6)(x - 5).
