Question

What are the solutions to the equation 0=x2-x-6? Select two options

X=-3
X=-2
X=0
X=2
X=3

Answer 1

Answer: b,e

Explanation:

Answer 2

The correct options are,

x = -2 and x = 3

Explanation:

It is given that,

x² - x - 6 = 0

To find the solution of given equation

x² - x - 6 = 0 can be written as

x² + 2x - 3x - 6 = 0

x(x + 2) - 3( x + 2) = =

(x + 2)(x - 3) = 0

Either (x + 2) = 0 or (x - 3) = 0

If (x + 2) = 0 then x = -2

If (x - 3) = 0 then x = 3

Therefore the correct options are,

x = -2 and x = 3
