6x11÷2
6 x 11 is 66
66 ÷ 2 is 33
The answer is 33
This does not have a cube root. It has a CUBIC (degree 3) term.
In Algebra II we learn about rational roots theorem, synthetic division, and Descartes' rule of signs.
It happens that 2 is a root, so x-2 is a factor.
When we divide this synthetically, we obtain the depressed polynomial (other) factor as x2+3x +6.
Cosine of 60 and Cosine of 30
