Question

Solve each equation with the quadratic formula:

10x^2-12x-2=0

Answer 1

/ by 2
5x^2 - 6x -1 = 0
x =( --6 +- sqrt(36 - 4* 5 * -1) / 10

Answer 2

\[(-b \pm \sqrt{b^2-4ac})/2a\]

Answer 3

First imagine the formula as\[ax^2+bx+c=0\]
then put it into the formula
\[x=(-b \pm \sqrt{b^2-4ac})/2a\]

Answer 4

I know the quadratic formula, and I forgot to divide everything by 2 in the beginning. Thanks, I can do it now.
