Question

Utilizar a fórmula de Bhaskara pra resolver as seguintes equações do 2° grau:

x²-5x+6 = 0

x²-8x+12 = 0

x²+2x-8= 0

Answer 1

x²-5x+6 = 0
∆=25-4.1.6
∆=26-24
∆=2
X1=5+√2/2
x2=5-√2/2


x²-8x+12 = 0
∆=64-4.1.12
∆=64-48
∆=16
√∆=4
x1=8+4/2=12/2=6
x2=8-4/2=4/2=2


x²+2x-8= 0
∆=4-4.1.(-8)
∆=4+32
∆=36
√∆=6
X1=-2+6/2=4/2=2
x2=-2-6/2=-8/2=-4
