Question

3x²-6x+2



factorise it☺​

Answer 1

Answer:

$3x^{2}-6x+2$

a = 3

b = -6

c = 2

$\frac{-b±\sqrt{b^{2}-4ac}}{2a}\\\\=\frac{-(-6)±\sqrt{(-6)^{2}-4(3)(2)}}{2(3)}\\\\= \frac{6±\sqrt{36-24}}{6}\\\\=\frac{6±\sqrt{12}}{6}\\\\=\frac{6±2\sqrt{3}}{6}$

$x=\frac{2(3+\sqrt{3})}{6}\\\\x=\frac{3+\sqrt{3}}{3}$

&

$x=\frac{2(3-\sqrt{3})}{6}\\\\x=\frac{3-\sqrt{3}}{3}$
