Solution for 0=21w^2+2w equation:


Simplifying
0 = 21w2 + 2w

Reorder the terms:
0 = 2w + 21w2

Solving
0 = 2w + 21w2

Solving for variable 'w'.
Remove the zero:
-2w + -21w2 = 2w + 21w2 + -2w + -21w2

Reorder the terms:
-2w + -21w2 = 2w + -2w + 21w2 + -21w2

Combine like terms: 2w + -2w = 0
-2w + -21w2 = 0 + 21w2 + -21w2
-2w + -21w2 = 21w2 + -21w2

Combine like terms: 21w2 + -21w2 = 0
-2w + -21w2 = 0

Factor out the Greatest Common Factor (GCF), '-1w'.
-1w(2 + 21w) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'w' equal to zero and attempt to solve: Simplifying w = 0 Solving w = 0 Move all terms containing w to the left, all other terms to the right. Simplifying w = 0

Subproblem 2

Set the factor '(2 + 21w)' equal to zero and attempt to solve: Simplifying 2 + 21w = 0 Solving 2 + 21w = 0 Move all terms containing w to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 21w = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 21w = 0 + -2 21w = 0 + -2 Combine like terms: 0 + -2 = -2 21w = -2 Divide each side by '21'. w = -0.09523809524 Simplifying w = -0.09523809524

Solution

w = {0, -0.09523809524}
