Simplifying -2sinx = -5sin2(x) Multiply in2s * x -2insx = -5in2sx Solving -2insx = -5in2sx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Add '5in2sx' to each side of the equation. -2insx + 5in2sx = -5in2sx + 5in2sx Combine like terms: -5in2sx + 5in2sx = 0 -2insx + 5in2sx = 0 Factor out the Greatest Common Factor (GCF), 'insx'. insx(-2 + 5n) = 0Subproblem 1
Set the factor 'insx' equal to zero and attempt to solve: Simplifying insx = 0 Solving insx = 0 Move all terms containing i to the left, all other terms to the right. Simplifying insx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(-2 + 5n)' equal to zero and attempt to solve: Simplifying -2 + 5n = 0 Solving -2 + 5n = 0 Move all terms containing i to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + 5n = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 5n = 0 + 2 5n = 0 + 2 Combine like terms: 0 + 2 = 2 5n = 2 Add '-5n' to each side of the equation. 5n + -5n = 2 + -5n Combine like terms: 5n + -5n = 0 0 = 2 + -5n Simplifying 0 = 2 + -5n The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
