2(w*w)=-(7w+3)

Solution for 2(w*w)=-(7w+3) equation:

Simplifying
2(w * w) = -1(7w + 3)

Multiply w * w
2(w2) = -1(7w + 3)

Reorder the terms:
2w2 = -1(3 + 7w)
2w2 = (3 * -1 + 7w * -1)
2w2 = (-3 + -7w)

Solving
2w2 = -3 + -7w

Solving for variable 'w'.

Reorder the terms:
3 + 7w + 2w2 = -3 + -7w + 3 + 7w

Reorder the terms:
3 + 7w + 2w2 = -3 + 3 + -7w + 7w

Combine like terms: -3 + 3 = 0
3 + 7w + 2w2 = 0 + -7w + 7w
3 + 7w + 2w2 = -7w + 7w

Combine like terms: -7w + 7w = 0
3 + 7w + 2w2 = 0

Factor a trinomial.
(3 + w)(1 + 2w) = 0

Subproblem 1
Set the factor '(3 + w)' equal to zero and attempt to solve:

Simplifying
3 + w = 0

Solving
3 + w = 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 + w = 0 + -3

Combine like terms: 3 + -3 = 0
0 + w = 0 + -3
w = 0 + -3

Combine like terms: 0 + -3 = -3
w = -3

Simplifying
w = -3
Subproblem 2
Set the factor '(1 + 2w)' equal to zero and attempt to solve:

Simplifying
1 + 2w = 0

Solving
1 + 2w = 0

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

Add '-1' to each side of the equation.
1 + -1 + 2w = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 2w = 0 + -1
2w = 0 + -1

Combine like terms: 0 + -1 = -1
2w = -1

Divide each side by '2'.
w = -0.5

Simplifying
w = -0.5
Solution
w = {-3, -0.5}
