+A%5E4+%2B+3A%5E2+%2B+2A%5E3+-+5A+-+13+-+3A%5E0+-+A%5E1+ Start with the given expression.


+A%5E4+%2B+3A%5E2+%2B+2A%5E3+-+5A+-+13+-+3%281%29+-+A+ Raise "A" to the 0th power to get 1. Raise "A" to the 1st power to get "A"


+A%5E4+%2B+3A%5E2+%2B+2A%5E3+-+5A+-+13+-+3+-+A+ Multiply


+A%5E4+%2B+2A%5E3+%2B+3A%5E2++%2B%28-+5A+-+A%29+%2B%28-+13+-+3%29+ Rearrange and group like terms


+A%5E4+%2B+2A%5E3+%2B+3A%5E2++-6A+-16 Combine like terms.
