Question

qual a forma fatorada a equação x²-5x+6=0

Answer 1

x²-5x+6=0
x²-5x=-6
x=5+-$\sqrt \frac{(-5) ^{2}-4x1x6 }{2x1}$
x=5+-$\sqrt \frac{5 ^{2}-4x6 }{2}$
x=6+-$\sqrt \frac{25-24}{2}$
x=6+-$\sqrt \frac{1}{2}$
x=$\frac{5+-1}{2}$
$\left \{ {{x= \frac{5+1}{2} } \atop {x= \frac{5-1}{2} }} \right.$
$\left \{ {{x= \frac{6}{2} } \atop {x= \frac{4}{2} }} \right.$
$\left \{ {{x=3} \atop {x=2}} \right.$
X∈ {2,3}
