Question

X-6x+5=0 .....bbbbb me ajudemm

Answer 1

Boa noite!

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

$\Delta= b^{2} -4ac$

$-6^{2} -4.1.5$

$\Delta=36-20$

$\Delta=16$

$x= \frac{-b+- \sqrt{\Delta} }{2.a}$

$x= \frac{-(-6)+- \sqrt{16} }{2.1}$

$x= \frac{6+-4}{2}$

$x'= \frac{6+4}{2}$

$x'=5$

$x''= \frac{6-4}{2}$

$x''=1$

Espero ter ajudado.
