Question

How do I do 7x^2 + x + 2 = 0 by the quadratic formula.
Thanks for your help in advance!

Answer 1

do you know the quadratic formula?

Answer 2

I think so

Answer 3

ax^2 + bx + c = 0

7x^2 + 1x + 2 = 0

Answer 4

use those values for a, b , and c

Answer 5

a = 7 b = 1 c = 2?

Answer 6

yep..

\[x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]
