Step-by-step explanation:
9 = x/12
We will multiply 12 by 9
12 × 9 = x
108 = x

Answer: True</h3>
The key word here is "may" meaning that we could easily have 3 rational roots as well. An example of a cubic having 3 irrational roots would be
(x-1)(x-2)(x-3) = x³ - 6x² + 11x - 6
This has the rational roots x = 1, x = 2, x = 3.
However, we could easily replace 1,2,3 with any irrational numbers we want. So that's why the statement "a cubic has three irrational roots" is sometimes true.
In some cases, a cubic may only have 1 real root and the other 2 roots are imaginary.
Multiply to get it in standard from, which gives you the y-intercept as the constant.
for x, factor it all the way down and set the factors equal to zero. the answers are the x-intercepts
Half of the numbers between 1 to 10 are odd, 1,3,5,7,9.
So the probability is 1/2.
Hope this helps.
