(1+t^2)*0.35+t=0

Solution for (1+t^2)*0.35+t=0 equation:

Simplifying
(1 + t2) * 0.35 + t = 0

Reorder the terms for easier multiplication:
0.35(1 + t2) + t = 0
(1 * 0.35 + t2 * 0.35) + t = 0
(0.35 + 0.35t2) + t = 0

Reorder the terms:
0.35 + t + 0.35t2 = 0

Solving
0.35 + t + 0.35t2 = 0

Solving for variable 't'.

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

Divide each side by '0.35'.
1 + 2.857142857t + t2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 2.857142857t + -1 + t2 = 0 + -1

Reorder the terms:
1 + -1 + 2.857142857t + t2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 2.857142857t + t2 = 0 + -1
2.857142857t + t2 = 0 + -1

Combine like terms: 0 + -1 = -1
2.857142857t + t2 = -1

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.
2.857142857t + 0.25 + t2 = -1 + 0.25

Reorder the terms:
0.25 + 2.857142857t + t2 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + 2.857142857t + t2 = -0.75

Factor a perfect square on the left side:
(t + 0.5)(t + 0.5) = -0.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
