Rewrite the equation 2x+6x^(2)-1=3x^(2) in standard form and identify a, b, and c.

Fed [463]

Hi there!

$2x + 6 {x}^{2} - 1 = 3 {x}^{2}$
First subtract 3x^2 from both sides.

$2x + 3 {x}^{2} - 1 = 0$
Now rearrange the equation.

$3 {x}^{2} + 2x - 1 = 0$
Finally we can see our answer.

$a = 3$
$b = 2$
$c = - 1$
