You can put this solution on YOUR website! (5x^5-7)(x^8-2)
First = (5x^5)(x^8)
Outer = (5x^5)(-2)
Inner = (-7)(x^8)
Last = (-7)(-2)
= (5x^5)(x^8) + (5x^5)(-2) + (-7)(x^8) + (-7)(-2)__multiply
= 5x^5+8 - 10x^5 - 7x^8 + 14________________add exponents
= 5x^13 - 10x^5 - 7x^8 + 14_________________put in decending order g -> l
= 5x^13 - 7x^8 - 10x^5 + 14_________________Answer
