Solution for (2u^2)-3u-1=(u-3)(u-3) equation: 


Simplifying
(2u2) + -3u + -1 = (u + -3)(u + -3)

Reorder the terms:
-1 + -3u + (2u2) = (u + -3)(u + -3)

Reorder the terms:
-1 + -3u + (2u2) = (-3 + u)(u + -3)

Reorder the terms:
-1 + -3u + (2u2) = (-3 + u)(-3 + u)

Multiply (-3 + u) * (-3 + u)
-1 + -3u + (2u2) = (-3(-3 + u) + u(-3 + u))
-1 + -3u + (2u2) = ((-3 * -3 + u * -3) + u(-3 + u))
-1 + -3u + (2u2) = ((9 + -3u) + u(-3 + u))
-1 + -3u + (2u2) = (9 + -3u + (-3 * u + u * u))
-1 + -3u + (2u2) = (9 + -3u + (-3u + u2))

Combine like terms: -3u + -3u = -6u
-1 + -3u + (2u2) = (9 + -6u + u2)

Solving
-1 + -3u + (2u2) = 9 + -6u + u2

Solving for variable 'u'.

Reorder the terms:
-1 + -9 + -3u + 6u + (2u2) + -1u2 = 9 + -6u + u2 + -9 + 6u + -1u2

Combine like terms: -1 + -9 = -10
-10 + -3u + 6u + (2u2) + -1u2 = 9 + -6u + u2 + -9 + 6u + -1u2

Combine like terms: -3u + 6u = 3u
-10 + 3u + (2u2) + -1u2 = 9 + -6u + u2 + -9 + 6u + -1u2

Combine like terms: (2u2) + -1u2 = 1u2
-10 + 3u + 1u2 = 9 + -6u + u2 + -9 + 6u + -1u2

-10 + 3u + 1u2 = 9 + -9 + -6u + 6u + u2 + -1u2

Combine like terms: 9 + -9 = 0
-10 + 3u + 1u2 = 0 + -6u + 6u + u2 + -1u2
-10 + 3u + 1u2 = -6u + 6u + u2 + -1u2

Combine like terms: -6u + 6u = 0
-10 + 3u + 1u2 = 0 + u2 + -1u2
-10 + 3u + 1u2 = u2 + -1u2

Combine like terms: u2 + -1u2 = 0
-10 + 3u + 1u2 = 0
