You can use a technique called factoring by grouping to factor this expression:

#x^4-2x^3+5x-10# **Given**#(x^4-2x^3) + (5x-10)# **Insert parenthesis**

This allows you to pair the terms with like factors and factor them.

#x^3(x-2) +5(x-2)# **Greatest Common Factor**#(x-2)(x^3+5)# **Undo Distributive Property**
