Solution for Y=(X^2-X+7)(X^3+X) equation: 


Simplifying
Y = (X2 + -1X + 7)(X3 + X)

Reorder the terms:
Y = (7 + -1X + X2)(X3 + X)

Reorder the terms:
Y = (7 + -1X + X2)(X + X3)

Multiply (7 + -1X + X2) * (X + X3)
Y = (7(X + X3) + -1X * (X + X3) + X2(X + X3))
Y = ((X * 7 + X3 * 7) + -1X * (X + X3) + X2(X + X3))
Y = ((7X + 7X3) + -1X * (X + X3) + X2(X + X3))
Y = (7X + 7X3 + (X * -1X + X3 * -1X) + X2(X + X3))
Y = (7X + 7X3 + (-1X2 + -1X4) + X2(X + X3))
Y = (7X + 7X3 + -1X2 + -1X4 + (X * X2 + X3 * X2))
Y = (7X + 7X3 + -1X2 + -1X4 + (X3 + X5))

Reorder the terms:
Y = (7X + -1X2 + 7X3 + X3 + -1X4 + X5)

Combine like terms: 7X3 + X3 = 8X3
Y = (7X + -1X2 + 8X3 + -1X4 + X5)

Solving
Y = 7X + -1X2 + 8X3 + -1X4 + X5

Solving for variable 'Y'.
