(y+.33)(y-.33)=

Solution for (y+.33)(y-.33)= equation:

Simplifying
(y + 0.33)(y + -0.33) = 0

Reorder the terms:
(0.33 + y)(y + -0.33) = 0

Reorder the terms:
(0.33 + y)(-0.33 + y) = 0

Multiply (0.33 + y) * (-0.33 + y)
(0.33(-0.33 + y) + y(-0.33 + y)) = 0
((-0.33 * 0.33 + y * 0.33) + y(-0.33 + y)) = 0
((-0.1089 + 0.33y) + y(-0.33 + y)) = 0
(-0.1089 + 0.33y + (-0.33 * y + y * y)) = 0
(-0.1089 + 0.33y + (-0.33y + y2)) = 0

Combine like terms: 0.33y + -0.33y = 0.00
(-0.1089 + 0.00 + y2) = 0
(-0.1089 + y2) = 0

Solving
-0.1089 + y2 = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '0.1089' to each side of the equation.
-0.1089 + 0.1089 + y2 = 0 + 0.1089

Combine like terms: -0.1089 + 0.1089 = 0.0000
0.0000 + y2 = 0 + 0.1089
y2 = 0 + 0.1089

Combine like terms: 0 + 0.1089 = 0.1089
y2 = 0.1089

Simplifying
y2 = 0.1089

Take the square root of each side:
y = {-0.33, 0.33}
