Solution for (2x+1)(x-3)=44 equation:


Simplifying
(2x + 1)(x + -3) = 44

Reorder the terms:
(1 + 2x)(x + -3) = 44

Reorder the terms:
(1 + 2x)(-3 + x) = 44

Multiply (1 + 2x) * (-3 + x)
(1(-3 + x) + 2x * (-3 + x)) = 44
((-3 * 1 + x * 1) + 2x * (-3 + x)) = 44
((-3 + 1x) + 2x * (-3 + x)) = 44
(-3 + 1x + (-3 * 2x + x * 2x)) = 44
(-3 + 1x + (-6x + 2x2)) = 44

Combine like terms: 1x + -6x = -5x
(-3 + -5x + 2x2) = 44

Solving
-3 + -5x + 2x2 = 44

Solving for variable 'x'.

Reorder the terms:
-3 + -44 + -5x + 2x2 = 44 + -44

Combine like terms: -3 + -44 = -47
-47 + -5x + 2x2 = 44 + -44

Combine like terms: 44 + -44 = 0
-47 + -5x + 2x2 = 0

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

Divide each side by '2'.
-23.5 + -2.5x + x2 = 0

Move the constant term to the right:

Add '23.5' to each side of the equation.
-23.5 + -2.5x + 23.5 + x2 = 0 + 23.5

Reorder the terms:
-23.5 + 23.5 + -2.5x + x2 = 0 + 23.5

Combine like terms: -23.5 + 23.5 = 0.0
0.0 + -2.5x + x2 = 0 + 23.5
-2.5x + x2 = 0 + 23.5

Combine like terms: 0 + 23.5 = 23.5
-2.5x + x2 = 23.5

The x term is -2.5x.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5x + 1.5625 + x2 = 23.5 + 1.5625

Reorder the terms:
1.5625 + -2.5x + x2 = 23.5 + 1.5625

Combine like terms: 23.5 + 1.5625 = 25.0625
1.5625 + -2.5x + x2 = 25.0625
