Simplifying Sin2(7x) + -1sin2(4x) = 0 Remove parenthesis around (7x) in2S * 7x + -1sin2(4x) = 0 Reorder the terms for easier multiplication: 7in2S * x + -1sin2(4x) = 0 Multiply in2S * x 7in2xS + -1sin2(4x) = 0 Remove parenthesis around (4x) 7in2xS + -1in2s * 4x = 0 Reorder the terms for easier multiplication: 7in2xS + -1 * 4in2s * x = 0 Multiply -1 * 4 7in2xS + -4in2s * x = 0 Multiply in2s * x 7in2xS + -4in2sx = 0 Reorder the terms: -4in2sx + 7in2xS = 0 Solving -4in2sx + 7in2xS = 0 Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), 'in2x'. in2x(-4s + 7S) = 0Subproblem 1
Set the factor 'in2x' equal to zero and attempt to solve: Simplifying in2x = 0 Solving in2x = 0 Move all terms containing i to the left, all other terms to the right. Simplifying in2x = 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 '(-4s + 7S)' equal to zero and attempt to solve: Simplifying -4s + 7S = 0 Reorder the terms: 7S + -4s = 0 Solving 7S + -4s = 0 Move all terms containing i to the left, all other terms to the right. Add '-7S' to each side of the equation. 7S + -7S + -4s = 0 + -7S Combine like terms: 7S + -7S = 0 0 + -4s = 0 + -7S -4s = 0 + -7S Remove the zero: -4s = -7S Add '4s' to each side of the equation. -4s + 4s = -7S + 4s Combine like terms: -4s + 4s = 0 0 = -7S + 4s Simplifying 0 = -7S + 4s 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.
