Question

Y=X2-2X+1 FORMA DE BHASCARA

Answer 1

y = x² - 2x + 1

===
Δ = b²−4ac
Δ = (−2)²−4⋅1⋅1
Δ = 4−4
Δ = 0

$x = \dfrac{-b \pm \sqrt{\Delta}}{2*a}\\ \\ \\ x = \dfrac{-(-2) \pm \sqrt{0}}{2*1}\\ \\ \\ x = \dfrac{2 \pm 0}{2}\\ \\ \\ x' = \dfrac{2 - 0}{2}\\ \\ \\ x' = \dfrac{2}{2}\\ \\ \\ x' = 1\\ \\ \\ x'' = \dfrac{2 + 0}{2}\\ \\ \\ x'' = \dfrac{2}{2}\\ \\ \\ x'' = 1$
