-t^2-t=3

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

Simplifying
-1t2 + -1t = 3

Reorder the terms:
-1t + -1t2 = 3

Solving
-1t + -1t2 = 3

Solving for variable 't'.

Reorder the terms:
-3 + -1t + -1t2 = 3 + -3

Combine like terms: 3 + -3 = 0
-3 + -1t + -1t2 = 0

Factor out the Greatest Common Factor (GCF), '-1'.
-1(3 + t + t2) = 0

Ignore the factor -1.
Subproblem 1
Set the factor '(3 + t + t2)' equal to zero and attempt to solve:

Simplifying
3 + t + t2 = 0

Solving
3 + t + t2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + t + -3 + t2 = 0 + -3

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

Combine like terms: 3 + -3 = 0
0 + t + t2 = 0 + -3
t + t2 = 0 + -3

Combine like terms: 0 + -3 = -3
t + t2 = -3

The t term is t.  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.
t + 0.25 + t2 = -3 + 0.25

Reorder the terms:
0.25 + t + t2 = -3 + 0.25

Combine like terms: -3 + 0.25 = -2.75
0.25 + t + t2 = -2.75

Factor a perfect square on the left side:
(t + 0.5)(t + 0.5) = -2.75

Can't calculate square root of the right side.
