t^2-4t+16=0

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

Simplifying
t2 + -4t + 16 = 0

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

Solving
16 + -4t + t2 = 0

Solving for variable 't'.

Begin completing the square.

Move the constant term to the right:

Add '-16' to each side of the equation.
16 + -4t + -16 + t2 = 0 + -16

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

Combine like terms: 16 + -16 = 0
0 + -4t + t2 = 0 + -16
-4t + t2 = 0 + -16

Combine like terms: 0 + -16 = -16
-4t + t2 = -16

The t term is -4t.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4t + 4 + t2 = -16 + 4

Reorder the terms:
4 + -4t + t2 = -16 + 4

Combine like terms: -16 + 4 = -12
4 + -4t + t2 = -12

Factor a perfect square on the left side:
(t + -2)(t + -2) = -12

Can't calculate square root of the right side.
