2(x-5)(x+0.5)=0

Solution for 2(x-5)(x+0.5)=0 equation:

Simplifying
2(x + -5)(x + 0.5) = 0

Reorder the terms:
2(-5 + x)(x + 0.5) = 0

Reorder the terms:
2(-5 + x)(0.5 + x) = 0

Multiply (-5 + x) * (0.5 + x)
2(-5(0.5 + x) + x(0.5 + x)) = 0
2((0.5 * -5 + x * -5) + x(0.5 + x)) = 0
2((-2.5 + -5x) + x(0.5 + x)) = 0
2(-2.5 + -5x + (0.5 * x + x * x)) = 0
2(-2.5 + -5x + (0.5x + x2)) = 0

Combine like terms: -5x + 0.5x = -4.5x
2(-2.5 + -4.5x + x2) = 0
(-2.5 * 2 + -4.5x * 2 + x2 * 2) = 0
(-5 + -9x + 2x2) = 0

Solving
-5 + -9x + 2x2 = 0

Solving for variable 'x'.
