-2t2 + 5t = 4

Reorder the terms:
5t + -2t2 = 4

Solving
5t + -2t2 = 4

Solving for variable 't'.

Reorder the terms:
-4 + 5t + -2t2 = 4 + -4

Combine like terms: 4 + -4 = 0
-4 + 5t + -2t2 = 0

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

Divide each side by '-2'.
2 + -2.5t + t2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + -2.5t + -2 + t2 = 0 + -2

Reorder the terms:
2 + -2 + -2.5t + t2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -2.5t + t2 = 0 + -2
-2.5t + t2 = 0 + -2

Combine like terms: 0 + -2 = -2
-2.5t + t2 = -2

The t term is -2.5t.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5t + 1.5625 + t2 = -2 + 1.5625

Reorder the terms:
1.5625 + -2.5t + t2 = -2 + 1.5625

Combine like terms: -2 + 1.5625 = -0.4375
1.5625 + -2.5t + t2 = -0.4375

Factor a perfect square on the left side:
(t + -1.25)(t + -1.25) = -0.4375
