Solution for 5(v+2)3(v+5)=1 equation:


Simplifying
5(v + 2) * 3(v + 5) = 1

Reorder the terms:
5(2 + v) * 3(v + 5) = 1

Reorder the terms:
5(2 + v) * 3(5 + v) = 1

Reorder the terms for easier multiplication:
5 * 3(2 + v)(5 + v) = 1

Multiply 5 * 3
15(2 + v)(5 + v) = 1

Multiply (2 + v) * (5 + v)
15(2(5 + v) + v(5 + v)) = 1
15((5 * 2 + v * 2) + v(5 + v)) = 1
15((10 + 2v) + v(5 + v)) = 1
15(10 + 2v + (5 * v + v * v)) = 1
15(10 + 2v + (5v + v2)) = 1

Combine like terms: 2v + 5v = 7v
15(10 + 7v + v2) = 1
(10 * 15 + 7v * 15 + v2 * 15) = 1
(150 + 105v + 15v2) = 1

Solving
150 + 105v + 15v2 = 1

Solving for variable 'v'.

Reorder the terms:
150 + -1 + 105v + 15v2 = 1 + -1

Combine like terms: 150 + -1 = 149
149 + 105v + 15v2 = 1 + -1

Combine like terms: 1 + -1 = 0
149 + 105v + 15v2 = 0

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

Divide each side by '15'.
9.933333333 + 7v + v2 = 0

Move the constant term to the right:

Add '-9.933333333' to each side of the equation.
9.933333333 + 7v + -9.933333333 + v2 = 0 + -9.933333333

Reorder the terms:
9.933333333 + -9.933333333 + 7v + v2 = 0 + -9.933333333

Combine like terms: 9.933333333 + -9.933333333 = 0.000000000
0.000000000 + 7v + v2 = 0 + -9.933333333
7v + v2 = 0 + -9.933333333

Combine like terms: 0 + -9.933333333 = -9.933333333
7v + v2 = -9.933333333

The v term is 7v.  Take half its coefficient (3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
7v + 12.25 + v2 = -9.933333333 + 12.25

Reorder the terms:
12.25 + 7v + v2 = -9.933333333 + 12.25

Combine like terms: -9.933333333 + 12.25 = 2.316666667
12.25 + 7v + v2 = 2.316666667

Factor a perfect square on the left side:
(v + 3.5)(v + 3.5) = 2.316666667

Calculate the square root of the right side: 1.522060008

Break this problem into two subproblems by setting 
(v + 3.5) equal to 1.522060008 and -1.522060008.

Subproblem 1

v + 3.5 = 1.522060008 Simplifying v + 3.5 = 1.522060008 Reorder the terms: 3.5 + v = 1.522060008 Solving 3.5 + v = 1.522060008 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + v = 1.522060008 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + v = 1.522060008 + -3.5 v = 1.522060008 + -3.5 Combine like terms: 1.522060008 + -3.5 = -1.977939992 v = -1.977939992 Simplifying v = -1.977939992

Subproblem 2

v + 3.5 = -1.522060008 Simplifying v + 3.5 = -1.522060008 Reorder the terms: 3.5 + v = -1.522060008 Solving 3.5 + v = -1.522060008 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + v = -1.522060008 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + v = -1.522060008 + -3.5 v = -1.522060008 + -3.5 Combine like terms: -1.522060008 + -3.5 = -5.022060008 v = -5.022060008 Simplifying v = -5.022060008

Solution

The solution to the problem is based on the solutions from the subproblems. v = {-1.977939992, -5.022060008}
