Solution for (X+0.75)(X-6)(X+1)=Y equation: 


Simplifying
(X + 0.75)(X + -6)(X + 1) = Y

Reorder the terms:
(0.75 + X)(X + -6)(X + 1) = Y

Reorder the terms:
(0.75 + X)(-6 + X)(X + 1) = Y

Reorder the terms:
(0.75 + X)(-6 + X)(1 + X) = Y

Multiply (0.75 + X) * (-6 + X)
(0.75(-6 + X) + X(-6 + X))(1 + X) = Y
((-6 * 0.75 + X * 0.75) + X(-6 + X))(1 + X) = Y
((-4.5 + 0.75X) + X(-6 + X))(1 + X) = Y
(-4.5 + 0.75X + (-6 * X + X * X))(1 + X) = Y
(-4.5 + 0.75X + (-6X + X2))(1 + X) = Y

Combine like terms: 0.75X + -6X = -5.25X
(-4.5 + -5.25X + X2)(1 + X) = Y

Multiply (-4.5 + -5.25X + X2) * (1 + X)
(-4.5(1 + X) + -5.25X * (1 + X) + X2(1 + X)) = Y
((1 * -4.5 + X * -4.5) + -5.25X * (1 + X) + X2(1 + X)) = Y
((-4.5 + -4.5X) + -5.25X * (1 + X) + X2(1 + X)) = Y
(-4.5 + -4.5X + (1 * -5.25X + X * -5.25X) + X2(1 + X)) = Y
(-4.5 + -4.5X + (-5.25X + -5.25X2) + X2(1 + X)) = Y
(-4.5 + -4.5X + -5.25X + -5.25X2 + (1 * X2 + X * X2)) = Y
(-4.5 + -4.5X + -5.25X + -5.25X2 + (1X2 + X3)) = Y

Combine like terms: -4.5X + -5.25X = -9.75X
(-4.5 + -9.75X + -5.25X2 + 1X2 + X3) = Y

Combine like terms: -5.25X2 + 1X2 = -4.25X2
(-4.5 + -9.75X + -4.25X2 + X3) = Y

Solving
-4.5 + -9.75X + -4.25X2 + X3 = Y

Solving for variable 'X'.

Combine like terms: Y + -1Y = 0
-4.5 + -9.75X + -4.25X2 + X3 + -1Y = 0
