Solution for 4v^2-24v-5=0 equation:


Simplifying
4v2 + -24v + -5 = 0

Reorder the terms:
-5 + -24v + 4v2 = 0

Solving
-5 + -24v + 4v2 = 0

Solving for variable 'v'.

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

Divide each side by '4'.
-1.25 + -6v + v2 = 0

Move the constant term to the right:

Add '1.25' to each side of the equation.
-1.25 + -6v + 1.25 + v2 = 0 + 1.25

Reorder the terms:
-1.25 + 1.25 + -6v + v2 = 0 + 1.25

Combine like terms: -1.25 + 1.25 = 0.00
0.00 + -6v + v2 = 0 + 1.25
-6v + v2 = 0 + 1.25

Combine like terms: 0 + 1.25 = 1.25
-6v + v2 = 1.25

The v term is -6v.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6v + 9 + v2 = 1.25 + 9

Reorder the terms:
9 + -6v + v2 = 1.25 + 9

Combine like terms: 1.25 + 9 = 10.25
9 + -6v + v2 = 10.25

Factor a perfect square on the left side:
(v + -3)(v + -3) = 10.25

Calculate the square root of the right side: 3.201562119

Break this problem into two subproblems by setting 
(v + -3) equal to 3.201562119 and -3.201562119.

Subproblem 1

v + -3 = 3.201562119 Simplifying v + -3 = 3.201562119 Reorder the terms: -3 + v = 3.201562119 Solving -3 + v = 3.201562119 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + v = 3.201562119 + 3 Combine like terms: -3 + 3 = 0 0 + v = 3.201562119 + 3 v = 3.201562119 + 3 Combine like terms: 3.201562119 + 3 = 6.201562119 v = 6.201562119 Simplifying v = 6.201562119

Subproblem 2

v + -3 = -3.201562119 Simplifying v + -3 = -3.201562119 Reorder the terms: -3 + v = -3.201562119 Solving -3 + v = -3.201562119 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + v = -3.201562119 + 3 Combine like terms: -3 + 3 = 0 0 + v = -3.201562119 + 3 v = -3.201562119 + 3 Combine like terms: -3.201562119 + 3 = -0.201562119 v = -0.201562119 Simplifying v = -0.201562119

Solution
