3 = -18x

3/-18x

Change signs, time cant be negative.

x= 6

Another interpretation; Slope is negative it is falling. This interpretation is more accurate.

What are the solutions to the equation 0=x2-x-6? Select two options
shutvik [7]

Answer:

The correct options are,

x = -2 and x = 3

Step-by-step explanation:

It is given that,

x²  - x - 6 = 0

<u>To find the solution of given equation</u>

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
