Solution for 2Cos(2x)-8Cos(x)+6=Cos^2(x) equation:


Simplifying
2Cos(2x) + -8Cos(x) + 6 = Cos2(x)

Remove parenthesis around (2x)
2osC * 2x + -8Cos(x) + 6 = Cos2(x)

Reorder the terms for easier multiplication:
2 * 2osC * x + -8Cos(x) + 6 = Cos2(x)

Multiply 2 * 2
4osC * x + -8Cos(x) + 6 = Cos2(x)

Multiply osC * x
4osxC + -8Cos(x) + 6 = Cos2(x)

Multiply osC * x
4osxC + -8osxC + 6 = Cos2(x)

Reorder the terms:
6 + 4osxC + -8osxC = Cos2(x)

Combine like terms: 4osxC + -8osxC = -4osxC
6 + -4osxC = Cos2(x)

Multiply os2C * x
6 + -4osxC = os2xC

Solving
6 + -4osxC = os2xC

Solving for variable 'o'.

Move all terms containing o to the left, all other terms to the right.

Add '-1os2xC' to each side of the equation.
6 + -4osxC + -1os2xC = os2xC + -1os2xC
