Solution for =7sin^3(x^2+3x) equation: 


Simplifying
0 = 7sin3(x2 + 3x)

Reorder the terms:
0 = 7in3s(3x + x2)
0 = (3x * 7in3s + x2 * 7in3s)
0 = (21in3sx + 7in3sx2)

Solving
0 = 21in3sx + 7in3sx2

Solving for variable 'i'.

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

Add '-21in3sx' to each side of the equation.
0 + -21in3sx = 21in3sx + -21in3sx + 7in3sx2
Remove the zero:
-21in3sx = 21in3sx + -21in3sx + 7in3sx2

Combine like terms: 21in3sx + -21in3sx = 0
-21in3sx = 0 + 7in3sx2
-21in3sx = 7in3sx2

Add '-7in3sx2' to each side of the equation.
-21in3sx + -7in3sx2 = 7in3sx2 + -7in3sx2

Combine like terms: 7in3sx2 + -7in3sx2 = 0
-21in3sx + -7in3sx2 = 0

Factor out the Greatest Common Factor (GCF), '-7in3sx'.
-7in3sx(3 + x) = 0

Ignore the factor -7.

Subproblem 1
