Question

x2 -12X+36=0 por favor respondam urgente

Answer 1

x² - 12x+36= 0

Soma= -b    Produto= a.c

------- + -------= -b
------- x -------= a.c

6 + 6  =12
6 x 6  =36

As raízes são (6,6)

S= {6,6}

Answer 2

x² - 12 x + 36 =0
delta =b² - 4 .a.c
delta =(-12)² - 4 .1 .36
delta = 144 - 144
delta = 0
\/¨¨0 = 0
x = - b +ou -0/2.1
x = -(-12)/2
x = 12/ 2
x = 6
