Solution for 2t^2-11t+22=0 equation:


Simplifying
2t2 + -11t + 22 = 0

Reorder the terms:
22 + -11t + 2t2 = 0

Solving
22 + -11t + 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'.
11 + -5.5t + t2 = 0

Move the constant term to the right:

Add '-11' to each side of the equation.
11 + -5.5t + -11 + t2 = 0 + -11

Reorder the terms:
11 + -11 + -5.5t + t2 = 0 + -11

Combine like terms: 11 + -11 = 0
0 + -5.5t + t2 = 0 + -11
-5.5t + t2 = 0 + -11

Combine like terms: 0 + -11 = -11
-5.5t + t2 = -11

The t term is -5.5t.  Take half its coefficient (-2.75).
Square it (7.5625) and add it to both sides.

Add '7.5625' to each side of the equation.
-5.5t + 7.5625 + t2 = -11 + 7.5625

Reorder the terms:
7.5625 + -5.5t + t2 = -11 + 7.5625

Combine like terms: -11 + 7.5625 = -3.4375
7.5625 + -5.5t + t2 = -3.4375

Factor a perfect square on the left side:
(t + -2.75)(t + -2.75) = -3.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
