Question 311853: Solve by applying the Quadratic Formula; all radicals should be simplified as far as possible. Show your work
x^2 + 4x - 7 = 0

Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
x^2 + 4x - 7 = 0

x=(-4+-sqrt[4^2-4*1*-7])/2*1
x=(-4+-sqrt[16+28])/2
x=(-4sqrt44)/2
x=(-4+-6.633)/2
x=(-4+6.633)/2
x=2.633/2
x=1.317 ans.
x=(-4-6.633)/2
x=-10.633/2
x=-5.317 ans.
