Question

x²-10x+24=0 qual o resultado

Answer 1

$a=1; b=-10; c=24 \\ delta=b^2-4ac=(-10)^2-4*1*24=100-96=4 \\ x_{1} = \frac{-b+ \sqrt{delta} }{2a} ; x_{2} = \frac{-b- \sqrt{delta} }{2a} \\ x_{1} = \frac{-(-10)+ \sqrt{4} }{2*1} ; x_{2} = \frac{-(-10)- \sqrt{4} }{2a} \\ x_{1} = \frac{10+2 }{2} ; x_{2} = \frac{10-2}{2} \\ x_{1} = 6; x_{2} = 4$
