Ahhhh I see, thank you!

(a+b)^2 = a^2 + b^2

I am not sure what you mean?

Homework Statement I can't determine where the 40x comes from. From: 4x + 5 = 8√(1 - x) To: 16x^2 +40x + 25 = 64 - 64x^2 Homework Equations √1-x^2 = √1-x *√x+1 The Attempt at a Solution 4x + 5 = 8√(1-x) 4x^2 + 5^2 = (8 - 8x)*(8x + 8) 16x^2 +25 = 64 - 64x^2

I have found solutions to a question I am trying to figure out, and I am unsure how they got from one step to the next. Is it some sort of integration?? Eqn 1) 0.625 = sin(theta) - 0.5cos(theta) Eqn 2) 0.625 = sqrt(1 - x^2) - 0.5x
