Solution for 8t^2-2t+7= equation:


Simplifying
8t2 + -2t + 7 = 0

Reorder the terms:
7 + -2t + 8t2 = 0

Solving
7 + -2t + 8t2 = 0

Solving for variable 't'.

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

Divide each side by '8'.
0.875 + -0.25t + t2 = 0

Move the constant term to the right:

Add '-0.875' to each side of the equation.
0.875 + -0.25t + -0.875 + t2 = 0 + -0.875

Reorder the terms:
0.875 + -0.875 + -0.25t + t2 = 0 + -0.875

Combine like terms: 0.875 + -0.875 = 0.000
0.000 + -0.25t + t2 = 0 + -0.875
-0.25t + t2 = 0 + -0.875

Combine like terms: 0 + -0.875 = -0.875
-0.25t + t2 = -0.875

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 = -0.875 + 0.015625

Reorder the terms:
0.015625 + -0.25t + t2 = -0.875 + 0.015625

Combine like terms: -0.875 + 0.015625 = -0.859375
0.015625 + -0.25t + t2 = -0.859375

Factor a perfect square on the left side:
(t + -0.125)(t + -0.125) = -0.859375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
