Solution for (w+3)(w-10)=0 equation:


Simplifying
(w + 3)(w + -10) = 0

Reorder the terms:
(3 + w)(w + -10) = 0

Reorder the terms:
(3 + w)(-10 + w) = 0

Multiply (3 + w) * (-10 + w)
(3(-10 + w) + w(-10 + w)) = 0
((-10 * 3 + w * 3) + w(-10 + w)) = 0
((-30 + 3w) + w(-10 + w)) = 0
(-30 + 3w + (-10 * w + w * w)) = 0
(-30 + 3w + (-10w + w2)) = 0

Combine like terms: 3w + -10w = -7w
(-30 + -7w + w2) = 0

Solving
-30 + -7w + w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-3 + -1w)(10 + -1w) = 0

Subproblem 1

Set the factor '(-3 + -1w)' equal to zero and attempt to solve: Simplifying -3 + -1w = 0 Solving -3 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + -1w = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1w = 0 + 3 -1w = 0 + 3 Combine like terms: 0 + 3 = 3 -1w = 3 Divide each side by '-1'. w = -3 Simplifying w = -3

Subproblem 2

Set the factor '(10 + -1w)' equal to zero and attempt to solve: Simplifying 10 + -1w = 0 Solving 10 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -1w = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -1w = 0 + -10 -1w = 0 + -10 Combine like terms: 0 + -10 = -10 -1w = -10 Divide each side by '-1'. w = 10 Simplifying w = 10

Solution

w = {-3, 10}
