How do you prove this?
Is sin2xsinx-cosx = -(3root3)/2 true for 7pi/6? Explain.

I am not sure how to solve this.
3x+4y=9 4x-37=-13
x2-9y2-4x-18y=14
Both number twos are squared. I know the answer is 12(x-4)2+5. the number 2 is squared. can you show me how to work out please .thank you
Solve by completing the square. The Number two after the X is squared. I know the answer is x=-4 or X=5/2 could you please show how to get that.
So it would be 3x*2x+xy -2x for the two boxes that are x*x
