Answer:
Step-by-step explanation:
<u>Solving</u>
- | 6x² + x - 2 | + | 2 + 3x - 9x² | = | 4x - 3x² |
- 6x² + x - 2 + 2 + 3x - 9x² = 4x - 3x²
- -3x² + 4x = 4x - 3x²
- <u>x = ∞</u>
- Any value is possible as long as it is positive and a real number
<h3>
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.
Answer:
the information is in the theorem itself and to prove it set up an equation in the same format the theorem uses and test it.
