Solution for 16t^2+4t+5=0 equation:


Simplifying
16t2 + 4t + 5 = 0

Reorder the terms:
5 + 4t + 16t2 = 0

Solving
5 + 4t + 16t2 = 0

Solving for variable 't'.

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

Divide each side by '16'.
0.3125 + 0.25t + t2 = 0

Move the constant term to the right:

Add '-0.3125' to each side of the equation.
0.3125 + 0.25t + -0.3125 + t2 = 0 + -0.3125

Reorder the terms:
0.3125 + -0.3125 + 0.25t + t2 = 0 + -0.3125

Combine like terms: 0.3125 + -0.3125 = 0.0000
0.0000 + 0.25t + t2 = 0 + -0.3125
0.25t + t2 = 0 + -0.3125

Combine like terms: 0 + -0.3125 = -0.3125
0.25t + t2 = -0.3125

The t term is 0.25t.  Take half its coefficient (0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
0.25t + 0.015625 + t2 = -0.3125 + 0.015625

Reorder the terms:
0.015625 + 0.25t + t2 = -0.3125 + 0.015625

Combine like terms: -0.3125 + 0.015625 = -0.296875
0.015625 + 0.25t + t2 = -0.296875

Factor a perfect square on the left side:
(t + 0.125)(t + 0.125) = -0.296875

Can't calculate square root of the right side.

The solution to this equation could not be determined.
