Hi! I need help with this question! The answer is (a=10 b=1 c=-2) OR (a=-10 b=-1 c=2)

Its from w13_qp_42

Thanks in advance!

2 - x - 3x^3 = 10x^2 - 3x^3
2 - x = 10x^2
2- x - 10x^2 = 0
-10x^2 -x + 2 = 0
-( 10x^2 + x -2)=0
10x^2 + x - 2 = 0
So a = 10 b= 1 and c = -2

Hi guys, can anybody please tell me how to find an angle using the cosine rule? I know the formula is a squared= b squared + c squared - 2bc cos A but it can only be used to find the side, not the angle??????
