Answer:
3/2x^3
Step-by-step explanation:
multiply the numerators and the denominators
You have two binomials. I would just FOIL them:
First: 4 x 2 = 8
Outside: 4 (-√3) = -4√3
Inside: -3√3 (2) = -6√3
Last: -3√3 (-√3) = 9
Addummup: 8 - 4√3 - -6√3 + 9 = 17 - 10√3
96/120=0.8
1-0.8=0.2
put it into percentage--> 0.2*100=20%
it is 20% off.
