is these answers correct?
solve the equation: 2x^2 +8x  17=(x +2)^2= x=7,3
solve (v5)^263=0, where v is a real number, simplify answer as much as possible. v=3 square root 7+5,3 square root7+5
v``12.93725, 2.937254
use the quadratic formula to solve for x.
4x^2x4=0
=x=1+squar root65/8 , 1square root65/8=x``1.132782,0.882782

sorry I have a few more and I need the answers quick!!
Find the value: ^3 square root 27= 9
Write the following in simlpified radical form: ^4 square root 80= 4
Solve for x, where x is real number: square 5x + 9= square root 9x + 13=27
