Re: Add: (4s^5-s^4+8)+(6s^5-s-2)? and Add: (7x^3-7x^6-7)+(-5x^6+5-7x^3)?

Add:
(4s^5 - s^4 + 8) + (6s^5 - s - 2)
= 4s^5 - s^4 + 8 + 6s^5 - s - 2 {took out parentheses}
= 10s^5 - s^4 - s + 6 {combined like terms and wrote in decreasing order of exponents}

Add:
(7x^3 - 7x^6 - 7) + (-5x^6 + 5 -7x^3)
= 7x^3 - 7x^6 - 7 - 5x^6 + 5 - 7x^3 {took out parentheses}
= -12x^6 - 2 {combined like terms}
