Question

x^2-x-6=0

Answer 1

Do you know a formula of Discriminant?

Answer 2

and do you need to solve an equation?

Answer 3

use middle term splitting

Answer 4

\[x ^{2} - x - 6 = 0\]

Answer 5

\[x ^{2} - (3-2)x - 6 = 0\]

Answer 6

\[x ^{2} - 3x + 2x - 6 = 0\]
x(x-3) + 2(x-3) = 0
(x-3)(x+2) = 0

Answer 7

x-3 = 0 & x+2 = 0
x=3 & x=-2
