Divide each side by '10'.
2.1 + -2.4x + x2 = 0

Move the constant term to the right:

Add '-2.1' to each side of the equation.
2.1 + -2.4x + -2.1 + x2 = 0 + -2.1

Reorder the terms:
2.1 + -2.1 + -2.4x + x2 = 0 + -2.1

Combine like terms: 2.1 + -2.1 = 0.0
0.0 + -2.4x + x2 = 0 + -2.1
-2.4x + x2 = 0 + -2.1

Combine like terms: 0 + -2.1 = -2.1
-2.4x + x2 = -2.1

The x term is -2.4x.  Take half its coefficient (-1.2).
Square it (1.44) and add it to both sides.
