Your equation is: $y=3(x-1)(x+6)$
Firstly, expand the brackets

directrix · Answer

> y=3(x-1)(x+6)
The x-intercepts lie on the x-axis and have a y-value of 0.
So, you want to solve 0 = 3(x-1)(x+6)
Divide both sides by 3.
0 = (x-1)(x+6)

directrix · Answer

Apply the Zero Product Property to get:

0 = (x-1)(x+6)

so 0 = x -1 or 0 = x + 6
x = ? or x = ?

After you solve for x, be careful to place the x-intercepts in the proper position in the (x,y) format. (1,0) and (-6,0) is not the same as (0,1) and (0,-6).
