Solution for (4-w)(4w-1)=0 equation:


Simplifying
(4 + -1w)(4w + -1) = 0

Reorder the terms:
(4 + -1w)(-1 + 4w) = 0

Multiply (4 + -1w) * (-1 + 4w)
(4(-1 + 4w) + -1w * (-1 + 4w)) = 0
((-1 * 4 + 4w * 4) + -1w * (-1 + 4w)) = 0
((-4 + 16w) + -1w * (-1 + 4w)) = 0
(-4 + 16w + (-1 * -1w + 4w * -1w)) = 0
(-4 + 16w + (1w + -4w2)) = 0

Combine like terms: 16w + 1w = 17w
(-4 + 17w + -4w2) = 0

Solving
-4 + 17w + -4w2 = 0
