solve the equation: 2x^2 +8x - 17=(x +2)^2= x=-7,3

solve (v-5)^2-63=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^2x-4=0

=x=1+squar root65/8 , 1-square root65/8=x``1.132782,-0.882782

thank yu
