Solution for 4(w+5)(w-3)=4(w+5)(w)+240 equation:


Simplifying
4(w + 5)(w + -3) = 4(w + 5)(w) + 240

Reorder the terms:
4(5 + w)(w + -3) = 4(w + 5)(w) + 240

Reorder the terms:
4(5 + w)(-3 + w) = 4(w + 5)(w) + 240

Multiply (5 + w) * (-3 + w)
4(5(-3 + w) + w(-3 + w)) = 4(w + 5)(w) + 240
4((-3 * 5 + w * 5) + w(-3 + w)) = 4(w + 5)(w) + 240
4((-15 + 5w) + w(-3 + w)) = 4(w + 5)(w) + 240
4(-15 + 5w + (-3 * w + w * w)) = 4(w + 5)(w) + 240
4(-15 + 5w + (-3w + w2)) = 4(w + 5)(w) + 240

Combine like terms: 5w + -3w = 2w
4(-15 + 2w + w2) = 4(w + 5)(w) + 240
(-15 * 4 + 2w * 4 + w2 * 4) = 4(w + 5)(w) + 240
(-60 + 8w + 4w2) = 4(w + 5)(w) + 240

Reorder the terms:
-60 + 8w + 4w2 = 4(5 + w)(w) + 240

Reorder the terms for easier multiplication:
-60 + 8w + 4w2 = 4w(5 + w) + 240
-60 + 8w + 4w2 = (5 * 4w + w * 4w) + 240
-60 + 8w + 4w2 = (20w + 4w2) + 240

Reorder the terms:
-60 + 8w + 4w2 = 240 + 20w + 4w2

Add '-4w2' to each side of the equation.
-60 + 8w + 4w2 + -4w2 = 240 + 20w + 4w2 + -4w2

Combine like terms: 4w2 + -4w2 = 0
-60 + 8w + 0 = 240 + 20w + 4w2 + -4w2
-60 + 8w = 240 + 20w + 4w2 + -4w2

Combine like terms: 4w2 + -4w2 = 0
-60 + 8w = 240 + 20w + 0
-60 + 8w = 240 + 20w

Solving
-60 + 8w = 240 + 20w

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '-20w' to each side of the equation.
-60 + 8w + -20w = 240 + 20w + -20w

Combine like terms: 8w + -20w = -12w
-60 + -12w = 240 + 20w + -20w

Combine like terms: 20w + -20w = 0
-60 + -12w = 240 + 0
-60 + -12w = 240

Add '60' to each side of the equation.
-60 + 60 + -12w = 240 + 60

Combine like terms: -60 + 60 = 0
0 + -12w = 240 + 60
-12w = 240 + 60

Combine like terms: 240 + 60 = 300
-12w = 300

Divide each side by '-12'.
w = -25

Simplifying
w = -25
