(4w+5)(6-w)=0

Solution for (4w+5)(6-w)=0 equation:

Simplifying
(4w + 5)(6 + -1w) = 0

Reorder the terms:
(5 + 4w)(6 + -1w) = 0

Multiply (5 + 4w) * (6 + -1w)
(5(6 + -1w) + 4w * (6 + -1w)) = 0
((6 * 5 + -1w * 5) + 4w * (6 + -1w)) = 0
((30 + -5w) + 4w * (6 + -1w)) = 0
(30 + -5w + (6 * 4w + -1w * 4w)) = 0
(30 + -5w + (24w + -4w2)) = 0

Combine like terms: -5w + 24w = 19w
(30 + 19w + -4w2) = 0

Solving
30 + 19w + -4w2 = 0

Solving for variable 'w'.
