The solutions are

#### Explanation:

We can **Split the Middle Term** of this expression to factorise it.

In this technique, if we have to factorise an expression like

AND

After trying out a few numbers we get

**common factor** to each of the terms

We equate both factors to zero and obtain the solutions:

#x-4 = 0 , x = 4# #x+5 = 0, x=-5#
