Question

me ayudan porfavor ​

Answer 1

Respuesta:

La forma general es esta:

$\frac{-(b)\frac{+}{} \sqrt{(b^{2})-4(a)(c) } }{2(a)}$

* $x^{2} -5x+6=0$

$x=\frac{-(-5)\frac{+}{} \sqrt{(-5^{2})-4(1)(6) } }{2(1)}\\\\x=\frac{(5)\frac{+}{} \sqrt{(25)-(24) } }{(2)}\\\\x=\frac{(5)\frac{+}{} \sqrt{(1) } }{(2)}\\\\x=\frac{5\frac{+}{} 1 }{2}\\\\x_{1} =x=\frac{5+1 }{2}=3\\\\x_{2} =x=\frac{5-1 }{2}=2$
