Question

fatorar o trinomio Y=x²+x-6

Answer 1

Aplicando bhaskara vc encontra as raízes x= -3 e x=2, logo
y = (x+3)(x-2)

Answer 2

Y = x² + x - 6

x² + x - 6  = 0

x' = -1 - 5 / 2
x' = -6/2
x' = -3

x'' = -1 + 5 / 2
x'' = 4/2
x'' = 2


S = {-3,  2}

===

x' = -3
x + 3 = 0

x''= 2
x - 2 = 0

y = (x + 3).(x - 2)
