(x+0.67)(x-0.67)=

Solution for (x+0.67)(x-0.67)= equation:

Simplifying
(x + 0.67)(x + -0.67) = 0

Reorder the terms:
(0.67 + x)(x + -0.67) = 0

Reorder the terms:
(0.67 + x)(-0.67 + x) = 0

Multiply (0.67 + x) * (-0.67 + x)
(0.67(-0.67 + x) + x(-0.67 + x)) = 0
((-0.67 * 0.67 + x * 0.67) + x(-0.67 + x)) = 0
((-0.4489 + 0.67x) + x(-0.67 + x)) = 0
(-0.4489 + 0.67x + (-0.67 * x + x * x)) = 0
(-0.4489 + 0.67x + (-0.67x + x2)) = 0

Combine like terms: 0.67x + -0.67x = 0.00
(-0.4489 + 0.00 + x2) = 0
