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)
