Solution for 25t^2-25t-3=0 equation:


Simplifying
25t2 + -25t + -3 = 0

Reorder the terms:
-3 + -25t + 25t2 = 0

Solving
-3 + -25t + 25t2 = 0

Solving for variable 't'.

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

Divide each side by '25'.
-0.12 + -1t + t2 = 0

Move the constant term to the right:

Add '0.12' to each side of the equation.
-0.12 + -1t + 0.12 + t2 = 0 + 0.12

Reorder the terms:
-0.12 + 0.12 + -1t + t2 = 0 + 0.12

Combine like terms: -0.12 + 0.12 = 0.00
0.00 + -1t + t2 = 0 + 0.12
-1t + t2 = 0 + 0.12

Combine like terms: 0 + 0.12 = 0.12
-1t + t2 = 0.12

The t term is -1t.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1t + 0.25 + t2 = 0.12 + 0.25

Reorder the terms:
0.25 + -1t + t2 = 0.12 + 0.25

Combine like terms: 0.12 + 0.25 = 0.37
0.25 + -1t + t2 = 0.37

Factor a perfect square on the left side:
(t + -0.5)(t + -0.5) = 0.37

Calculate the square root of the right side: 0.608276253

Break this problem into two subproblems by setting 
(t + -0.5) equal to 0.608276253 and -0.608276253.

Subproblem 1

t + -0.5 = 0.608276253 Simplifying t + -0.5 = 0.608276253 Reorder the terms: -0.5 + t = 0.608276253 Solving -0.5 + t = 0.608276253 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + t = 0.608276253 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + t = 0.608276253 + 0.5 t = 0.608276253 + 0.5 Combine like terms: 0.608276253 + 0.5 = 1.108276253 t = 1.108276253 Simplifying t = 1.108276253

Subproblem 2

t + -0.5 = -0.608276253 Simplifying t + -0.5 = -0.608276253 Reorder the terms: -0.5 + t = -0.608276253 Solving -0.5 + t = -0.608276253 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + t = -0.608276253 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + t = -0.608276253 + 0.5 t = -0.608276253 + 0.5 Combine like terms: -0.608276253 + 0.5 = -0.108276253 t = -0.108276253 Simplifying t = -0.108276253
