Question

reslolva as equacoes x²-5x+6=0

Answer 1

$x = \frac{ - ( - 5) + - \sqrt{ {( - 5)}^{2} - 4 \times 1 \times 6} }{2 \times 1}$

$x = \frac{5 + - \sqrt{1} }{2}$

$x = \frac{5 + - 1}{2}$

$x1 = \frac{5 + 1}{2} = \frac{6}{2} = 3$

x2= 5-1/2 = 4/2 = 2

desculpe o modo que terminou, o app bugou

Answer 2

x²-5x+6=0                                   Baskara= b²-4.a.c

(-5)²-4.1.6  

Delta= 25-24= 1

x=  5 + ou - raiz de Delta / 2.a

x'= 6/2 = 3

x"= 4/2= 2

S=( 2,3)

Espero ter ajuda
