Question 185630
{{{ A^4 + 3A^2 + 2A^3 - 5A - 13 - 3A^0 - A^1 }}} Start with the given expression.



{{{ A^4 + 3A^2 + 2A^3 - 5A - 13 - 3(1) - A }}} Raise "A" to the 0th power to get 1. Raise "A" to the 1st power to get "A"



{{{ A^4 + 3A^2 + 2A^3 - 5A - 13 - 3 - A }}} Multiply



{{{ A^4 + 2A^3 + 3A^2  +(- 5A - A) +(- 13 - 3) }}} Rearrange and group like terms



{{{ A^4 + 2A^3 + 3A^2  -6A -16}}} Combine like terms.




So {{{ A^4 + 3A^2 + 2A^3 - 5A - 13 - 3A^0 - A^1=A^4 + 2A^3 + 3A^2  -6A -16 }}}
