Question

Factorize:
$3x^2-14x+18$

Answer 1

$3x^2-14x+18$

Factor with discriminant method,

$x=\frac{14\pm \sqrt{{\left(-14\right)}^2-4\times 3\times 18}}{2\times 3}$

$x=\frac{14\pm \sqrt{20}i}{6}$

$=\left(x-\left(\frac{14-\sqrt{20}i}{6}\right)\right)\left(x-\left(\frac{14+\sqrt{20}i}{6}\right)\right)$
