Solution for F(x)=-0.2(x-1.9)(x-3.5) equation: 


Simplifying
F(x) = -0.2(x + -1.9)(x + -3.5)

Multiply F * x
xF = -0.2(x + -1.9)(x + -3.5)

Reorder the terms:
xF = -0.2(-1.9 + x)(x + -3.5)

Reorder the terms:
xF = -0.2(-1.9 + x)(-3.5 + x)

Multiply (-1.9 + x) * (-3.5 + x)
xF = -0.2(-1.9(-3.5 + x) + x(-3.5 + x))
xF = -0.2((-3.5 * -1.9 + x * -1.9) + x(-3.5 + x))
xF = -0.2((6.65 + -1.9x) + x(-3.5 + x))
xF = -0.2(6.65 + -1.9x + (-3.5 * x + x * x))
xF = -0.2(6.65 + -1.9x + (-3.5x + x2))

Combine like terms: -1.9x + -3.5x = -5.4x
xF = -0.2(6.65 + -5.4x + x2)
xF = (6.65 * -0.2 + -5.4x * -0.2 + x2 * -0.2)
xF = (-1.33 + 1.08x + -0.2x2)

Solving
xF = -1.33 + 1.08x + -0.2x2

Solving for variable 'x'.

Reorder the terms:
1.33 + -1.08x + xF + 0.2x2 = -1.33 + 1.08x + -0.2x2 + 1.33 + -1.08x + 0.2x2

Reorder the terms:
1.33 + -1.08x + xF + 0.2x2 = -1.33 + 1.33 + 1.08x + -1.08x + -0.2x2 + 0.2x2

Combine like terms: -1.33 + 1.33 = 0.00
1.33 + -1.08x + xF + 0.2x2 = 0.00 + 1.08x + -1.08x + -0.2x2 + 0.2x2
1.33 + -1.08x + xF + 0.2x2 = 1.08x + -1.08x + -0.2x2 + 0.2x2

Combine like terms: 1.08x + -1.08x = 0.00
1.33 + -1.08x + xF + 0.2x2 = 0.00 + -0.2x2 + 0.2x2
1.33 + -1.08x + xF + 0.2x2 = -0.2x2 + 0.2x2

Combine like terms: -0.2x2 + 0.2x2 = 0.0
1.33 + -1.08x + xF + 0.2x2 = 0.0
