Solution for y=(m^3+4m^2-9m)*(3m+7) equation: 


Simplifying
y = (m3 + 4m2 + -9m)(3m + 7)

Reorder the terms:
y = (-9m + 4m2 + m3)(3m + 7)

Reorder the terms:
y = (-9m + 4m2 + m3)(7 + 3m)

Multiply (-9m + 4m2 + m3) * (7 + 3m)
y = (-9m * (7 + 3m) + 4m2 * (7 + 3m) + m3(7 + 3m))
y = ((7 * -9m + 3m * -9m) + 4m2 * (7 + 3m) + m3(7 + 3m))
y = ((-63m + -27m2) + 4m2 * (7 + 3m) + m3(7 + 3m))
y = (-63m + -27m2 + (7 * 4m2 + 3m * 4m2) + m3(7 + 3m))
y = (-63m + -27m2 + (28m2 + 12m3) + m3(7 + 3m))
y = (-63m + -27m2 + 28m2 + 12m3 + (7 * m3 + 3m * m3))
y = (-63m + -27m2 + 28m2 + 12m3 + (7m3 + 3m4))

Combine like terms: -27m2 + 28m2 = 1m2
y = (-63m + 1m2 + 12m3 + 7m3 + 3m4)

Combine like terms: 12m3 + 7m3 = 19m3
y = (-63m + 1m2 + 19m3 + 3m4)

Solving
y = -63m + 1m2 + 19m3 + 3m4

Solving for variable 'y'.

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

Simplifying
y = -63m + 1m2 + 19m3 + 3m4
