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

Divide each side by '4.9'.
-12 + -4t + t2 = 0

Move the constant term to the right:

Add '12' to each side of the equation.
-12 + -4t + 12 + t2 = 0 + 12

Reorder the terms:
-12 + 12 + -4t + t2 = 0 + 12

Combine like terms: -12 + 12 = 0
0 + -4t + t2 = 0 + 12
-4t + t2 = 0 + 12

Combine like terms: 0 + 12 = 12
-4t + t2 = 12

The t term is -4t.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4t + 4 + t2 = 12 + 4

Reorder the terms:
4 + -4t + t2 = 12 + 4

Combine like terms: 12 + 4 = 16
4 + -4t + t2 = 16

Factor a perfect square on the left side:
(t + -2)(t + -2) = 16

Calculate the square root of the right side: 4

Break this problem into two subproblems by setting 
(t + -2) equal to 4 and -4.

Subproblem 1

t + -2 = 4 Simplifying t + -2 = 4 Reorder the terms: -2 + t = 4 Solving -2 + t = 4 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + t = 4 + 2 Combine like terms: -2 + 2 = 0 0 + t = 4 + 2 t = 4 + 2 Combine like terms: 4 + 2 = 6 t = 6 Simplifying t = 6

Subproblem 2

t + -2 = -4 Simplifying t + -2 = -4 Reorder the terms: -2 + t = -4 Solving -2 + t = -4 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + t = -4 + 2 Combine like terms: -2 + 2 = 0 0 + t = -4 + 2 t = -4 + 2 Combine like terms: -4 + 2 = -2 t = -2 Simplifying t = -2

Solution

The solution to the problem is based on the solutions from the subproblems. t = {6, -2}
