Solution for 2t^2-64t+45=0 equation:


Simplifying
2t2 + -64t + 45 = 0

Reorder the terms:
45 + -64t + 2t2 = 0

Solving
45 + -64t + 2t2 = 0

Solving for variable 't'.

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

Divide each side by '2'.
22.5 + -32t + t2 = 0

Move the constant term to the right:

Add '-22.5' to each side of the equation.
22.5 + -32t + -22.5 + t2 = 0 + -22.5

Reorder the terms:
22.5 + -22.5 + -32t + t2 = 0 + -22.5

Combine like terms: 22.5 + -22.5 = 0.0
0.0 + -32t + t2 = 0 + -22.5
-32t + t2 = 0 + -22.5

Combine like terms: 0 + -22.5 = -22.5
-32t + t2 = -22.5

The t term is -32t.  Take half its coefficient (-16).
Square it (256) and add it to both sides.

Add '256' to each side of the equation.
-32t + 256 + t2 = -22.5 + 256

Reorder the terms:
256 + -32t + t2 = -22.5 + 256

Combine like terms: -22.5 + 256 = 233.5
256 + -32t + t2 = 233.5

Factor a perfect square on the left side:
(t + -16)(t + -16) = 233.5

Calculate the square root of the right side: 15.28070679
