For the first one Answer:7z^3 −2z+1+2z^2
Step-by-step explanation:
(7z ^3
+ 4z −1)+(2z^2
− 6z +2)
Combine 4z and −6z to get −2z.
7z3 − 2z −1 + 2z2 +2
Add −1 and 2 to get 1.
7z3 − 2z + 1 + 2z2
Answer:
a) 7z³+2z²-2z+1
b)2x²+3x-8
Step-by-step explanation:
a) (7z³+4z-1)+(2z²-6z+2)
7z³+2z²-2z+1
b) (5x²-2x-1)-(3x²-5x+7)
5x²-2x-1-3x²+5x-7
2x²+3x-8
