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).
