Question

2x ao quadrADO - 6x +3 determine o vertice da funçao

Answer 1

vamos lá....

2x² - 6x + 3 = 0

a=2
b=-6
c=3

Δ=b²-4ac
Δ=(-6)²-4(2)(3)
Δ=36-24
Δ=12

$Xv= \frac{-b}{2a} = \frac{-(-6)}{2.2} = \frac{6}{4} = \frac{3}{2} \\ \\ Yv= \frac{-\Delta}{4a} = \frac{-12}{4.2} =- \frac{12}{8} =- \frac{3}{2}$
