Fórmula quadrática

Completando o quadrado

Fatoração

One step at a time

−x²+4x−3=0

Resolver com a fórmula quadrática

x_{1, 2}=−4± √4²−4(−1)(−3)2(−1)

√4²−4(−1)(−3)=2

x_{1, 2}=−4± 22(−1)

Separe as soluções

x₁=−4+22(−1) , x₂=−4−22(−1)

x=−4+22(−1) : 1

x=−4−22(−1) : 3

As soluções para a equação de segundo grau são:

x=1, x=3
