Answer: Root 3 / 3
Step-by-step explanation: Use unit circle trigonometry.
We can cosider this to be a difference of 2 squares so
4x^4 - 9x^2 = (2x^2 - 3x)(2x^2 + 3x) so D is one answer
also we could take x^2 out and get
x^2(4x^2 - 9) = C
Answer:

Step-by-step explanation:
5x2 – 15x – 20
10 – 15x – 20
