Answer:
(-2, 0), (1, 0)
Step-by-step explanation:
x-intercepts are when y equals 0. Therefore, replace y with 0. 0 = 3x² +3x - 6
Then, factor the equation. To do that, first take the GCF of the equation.
3(x² + x - 2). Then factor what is inside the parenthesis. This gives you
3(x+2)(x-1). Set each part containing an x equal to 0.
x+2 = 0 --> x = -2
x-1 = 0 --> x = 1
