(x+1.5)(x-1.5)=

Solution for (x+1.5)(x-1.5)= equation:

Simplifying
(x + 1.5)(x + -1.5) = 0

Reorder the terms:
(1.5 + x)(x + -1.5) = 0

Reorder the terms:
(1.5 + x)(-1.5 + x) = 0

Multiply (1.5 + x) * (-1.5 + x)
(1.5(-1.5 + x) + x(-1.5 + x)) = 0
((-1.5 * 1.5 + x * 1.5) + x(-1.5 + x)) = 0
((-2.25 + 1.5x) + x(-1.5 + x)) = 0
(-2.25 + 1.5x + (-1.5 * x + x * x)) = 0
(-2.25 + 1.5x + (-1.5x + x2)) = 0

Combine like terms: 1.5x + -1.5x = 0.0
(-2.25 + 0.0 + x2) = 0
(-2.25 + x2) = 0

Solving
-2.25 + x2 = 0

Solving for variable 'x'.

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

Add '2.25' to each side of the equation.
-2.25 + 2.25 + x2 = 0 + 2.25

Combine like terms: -2.25 + 2.25 = 0.00
0.00 + x2 = 0 + 2.25
x2 = 0 + 2.25

Combine like terms: 0 + 2.25 = 2.25
x2 = 2.25

Simplifying
x2 = 2.25

Take the square root of each side:
x = {-1.5, 1.5}
