0 = (-0.75 + x)(-0.75 + x)(2.05 + x)

Multiply (-0.75 + x) * (-0.75 + x)
0 = (-0.75(-0.75 + x) + x(-0.75 + x))(2.05 + x)
0 = ((-0.75 * -0.75 + x * -0.75) + x(-0.75 + x))(2.05 + x)
0 = ((0.5625 + -0.75x) + x(-0.75 + x))(2.05 + x)
0 = (0.5625 + -0.75x + (-0.75 * x + x * x))(2.05 + x)
0 = (0.5625 + -0.75x + (-0.75x + x2))(2.05 + x)

Combine like terms: -0.75x + -0.75x = -1.5x
0 = (0.5625 + -1.5x + x2)(2.05 + x)

Multiply (0.5625 + -1.5x + x2) * (2.05 + x)
0 = (0.5625(2.05 + x) + -1.5x * (2.05 + x) + x2(2.05 + x))
0 = ((2.05 * 0.5625 + x * 0.5625) + -1.5x * (2.05 + x) + x2(2.05 + x))
0 = ((1.153125 + 0.5625x) + -1.5x * (2.05 + x) + x2(2.05 + x))
0 = (1.153125 + 0.5625x + (2.05 * -1.5x + x * -1.5x) + x2(2.05 + x))
0 = (1.153125 + 0.5625x + (-3.075x + -1.5x2) + x2(2.05 + x))
0 = (1.153125 + 0.5625x + -3.075x + -1.5x2 + (2.05 * x2 + x * x2))
0 = (1.153125 + 0.5625x + -3.075x + -1.5x2 + (2.05x2 + x3))

Combine like terms: 0.5625x + -3.075x = -2.5125x
0 = (1.153125 + -2.5125x + -1.5x2 + 2.05x2 + x3)
