Solution for 9.39(1.6-x)(2.4-x)=0 equation:


Simplifying
9.39(1.6 + -1x)(2.4 + -1x) = 0

Multiply (1.6 + -1x) * (2.4 + -1x)
9.39(1.6(2.4 + -1x) + -1x * (2.4 + -1x)) = 0
9.39((2.4 * 1.6 + -1x * 1.6) + -1x * (2.4 + -1x)) = 0
9.39((3.84 + -1.6x) + -1x * (2.4 + -1x)) = 0
9.39(3.84 + -1.6x + (2.4 * -1x + -1x * -1x)) = 0
9.39(3.84 + -1.6x + (-2.4x + 1x2)) = 0

Combine like terms: -1.6x + -2.4x = -4x
9.39(3.84 + -4x + 1x2) = 0
(3.84 * 9.39 + -4x * 9.39 + 1x2 * 9.39) = 0
(36.0576 + -37.56x + 9.39x2) = 0

Solving
36.0576 + -37.56x + 9.39x2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
9.39 the coefficient of the squared term: 

Divide each side by '9.39'.
3.84 + -4x + x2 = 0

Move the constant term to the right:

Add '-3.84' to each side of the equation.
3.84 + -4x + -3.84 + x2 = 0 + -3.84

Reorder the terms:
3.84 + -3.84 + -4x + x2 = 0 + -3.84

Combine like terms: 3.84 + -3.84 = 0.00
0.00 + -4x + x2 = 0 + -3.84
-4x + x2 = 0 + -3.84

Combine like terms: 0 + -3.84 = -3.84
-4x + x2 = -3.84

The x term is -4x.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4x + 4 + x2 = -3.84 + 4

Reorder the terms:
4 + -4x + x2 = -3.84 + 4

Combine like terms: -3.84 + 4 = 0.16
4 + -4x + x2 = 0.16

Factor a perfect square on the left side:
(x + -2)(x + -2) = 0.16
