is these answers correct?
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
use the quadratic formula to solve for x.
=x=1+squar root65/8 , 1-square root65/8=x``1.132782,-0.882782
Need help quick please!! with provious questions on checking my answers.
the first one is correct
the second is correct
third, you have a typo in your equation
the answers are correct if the equation is
4x^2 - x - 4 = 0
could you please check this for me? Thanks
use the quadratic formula to solve for x. 4x^2-x-4=0
x=1+ square root 65/8, 1- square root 65/8 = 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
