I have already asked this question but I have to use my calculator to solve

x^2 + 8x + 5 = 0

Someone gave me a link to a quadratic formula solver but when I enter it into my calculator I nvever get the right answer.

    You can graph it, if you calc is a graphing calc. graph y=x^2+8x+5, where it crosses the x axis, is the solutions.

    I know but can you just tell me if this is correct:

    a = 1 b = 8 c= 5

    x= -8 + square root 8^2 - (4x1x5)
