Solution for 3w(w)-(w-5)(w-3)=2w(w)+1 equation:


Simplifying
3w(w) + -1(w + -5)(w + -3) = 2w(w) + 1

Multiply w * w
3w2 + -1(w + -5)(w + -3) = 2w(w) + 1

Reorder the terms:
3w2 + -1(-5 + w)(w + -3) = 2w(w) + 1

Reorder the terms:
3w2 + -1(-5 + w)(-3 + w) = 2w(w) + 1

Multiply (-5 + w) * (-3 + w)
3w2 + -1(-5(-3 + w) + w(-3 + w)) = 2w(w) + 1
3w2 + -1((-3 * -5 + w * -5) + w(-3 + w)) = 2w(w) + 1
3w2 + -1((15 + -5w) + w(-3 + w)) = 2w(w) + 1
3w2 + -1(15 + -5w + (-3 * w + w * w)) = 2w(w) + 1
3w2 + -1(15 + -5w + (-3w + w2)) = 2w(w) + 1

Combine like terms: -5w + -3w = -8w
3w2 + -1(15 + -8w + w2) = 2w(w) + 1
3w2 + (15 * -1 + -8w * -1 + w2 * -1) = 2w(w) + 1
3w2 + (-15 + 8w + -1w2) = 2w(w) + 1

Reorder the terms:
-15 + 8w + 3w2 + -1w2 = 2w(w) + 1

Combine like terms: 3w2 + -1w2 = 2w2
-15 + 8w + 2w2 = 2w(w) + 1

Multiply w * w
-15 + 8w + 2w2 = 2w2 + 1

Reorder the terms:
-15 + 8w + 2w2 = 1 + 2w2

Add '-2w2' to each side of the equation.
-15 + 8w + 2w2 + -2w2 = 1 + 2w2 + -2w2

Combine like terms: 2w2 + -2w2 = 0
-15 + 8w + 0 = 1 + 2w2 + -2w2
-15 + 8w = 1 + 2w2 + -2w2

Combine like terms: 2w2 + -2w2 = 0
-15 + 8w = 1 + 0
-15 + 8w = 1

Solving
-15 + 8w = 1

Solving for variable 'w'.

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

Add '15' to each side of the equation.
-15 + 15 + 8w = 1 + 15

Combine like terms: -15 + 15 = 0
0 + 8w = 1 + 15
8w = 1 + 15

Combine like terms: 1 + 15 = 16
8w = 16

Divide each side by '8'.
w = 2

Simplifying
w = 2
