Solution for 5t^2=2-2t equation:


Simplifying
5t2 = 2 + -2t

Solving
5t2 = 2 + -2t

Solving for variable 't'.

Reorder the terms:
-2 + 2t + 5t2 = 2 + -2t + -2 + 2t

Reorder the terms:
-2 + 2t + 5t2 = 2 + -2 + -2t + 2t

Combine like terms: 2 + -2 = 0
-2 + 2t + 5t2 = 0 + -2t + 2t
-2 + 2t + 5t2 = -2t + 2t

Combine like terms: -2t + 2t = 0
-2 + 2t + 5t2 = 0

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

Divide each side by '5'.
-0.4 + 0.4t + t2 = 0

Move the constant term to the right:

Add '0.4' to each side of the equation.
-0.4 + 0.4t + 0.4 + t2 = 0 + 0.4

Reorder the terms:
-0.4 + 0.4 + 0.4t + t2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + 0.4t + t2 = 0 + 0.4
0.4t + t2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
0.4t + t2 = 0.4

The t term is 0.4t.  Take half its coefficient (0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
0.4t + 0.04 + t2 = 0.4 + 0.04

Reorder the terms:
0.04 + 0.4t + t2 = 0.4 + 0.04

Combine like terms: 0.4 + 0.04 = 0.44
0.04 + 0.4t + t2 = 0.44

Factor a perfect square on the left side:
(t + 0.2)(t + 0.2) = 0.44

Calculate the square root of the right side: 0.663324958

Break this problem into two subproblems by setting 
(t + 0.2) equal to 0.663324958 and -0.663324958.

Subproblem 1

t + 0.2 = 0.663324958 Simplifying t + 0.2 = 0.663324958 Reorder the terms: 0.2 + t = 0.663324958 Solving 0.2 + t = 0.663324958 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + t = 0.663324958 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + t = 0.663324958 + -0.2 t = 0.663324958 + -0.2 Combine like terms: 0.663324958 + -0.2 = 0.463324958 t = 0.463324958 Simplifying t = 0.463324958

Subproblem 2

t + 0.2 = -0.663324958 Simplifying t + 0.2 = -0.663324958 Reorder the terms: 0.2 + t = -0.663324958 Solving 0.2 + t = -0.663324958 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + t = -0.663324958 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + t = -0.663324958 + -0.2 t = -0.663324958 + -0.2 Combine like terms: -0.663324958 + -0.2 = -0.863324958 t = -0.863324958 Simplifying t = -0.863324958

Solution

The solution to the problem is based on the solutions from the subproblems. t = {0.463324958, -0.863324958}
