Solution for 32-2t-5t^2=0 equation:


Simplifying
32 + -2t + -5t2 = 0

Solving
32 + -2t + -5t2 = 0

Solving for variable 't'.

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

Divide each side by '-5'.
-6.4 + 0.4t + t2 = 0

Move the constant term to the right:

Add '6.4' to each side of the equation.
-6.4 + 0.4t + 6.4 + t2 = 0 + 6.4

Reorder the terms:
-6.4 + 6.4 + 0.4t + t2 = 0 + 6.4

Combine like terms: -6.4 + 6.4 = 0.0
0.0 + 0.4t + t2 = 0 + 6.4
0.4t + t2 = 0 + 6.4

Combine like terms: 0 + 6.4 = 6.4
0.4t + t2 = 6.4

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 = 6.4 + 0.04

Reorder the terms:
0.04 + 0.4t + t2 = 6.4 + 0.04

Combine like terms: 6.4 + 0.04 = 6.44
0.04 + 0.4t + t2 = 6.44

Factor a perfect square on the left side:
(t + 0.2)(t + 0.2) = 6.44

Calculate the square root of the right side: 2.537715508

Break this problem into two subproblems by setting 
(t + 0.2) equal to 2.537715508 and -2.537715508.

Subproblem 1

t + 0.2 = 2.537715508 Simplifying t + 0.2 = 2.537715508 Reorder the terms: 0.2 + t = 2.537715508 Solving 0.2 + t = 2.537715508 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 = 2.537715508 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + t = 2.537715508 + -0.2 t = 2.537715508 + -0.2 Combine like terms: 2.537715508 + -0.2 = 2.337715508 t = 2.337715508 Simplifying t = 2.337715508

Subproblem 2

t + 0.2 = -2.537715508 Simplifying t + 0.2 = -2.537715508 Reorder the terms: 0.2 + t = -2.537715508 Solving 0.2 + t = -2.537715508 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 = -2.537715508 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + t = -2.537715508 + -0.2 t = -2.537715508 + -0.2 Combine like terms: -2.537715508 + -0.2 = -2.737715508 t = -2.737715508 Simplifying t = -2.737715508
