(x+14)(3x+1)=

Solution for (x+14)(3x+1)= equation:

Simplifying
(x + 14)(3x + 1) = 0

Reorder the terms:
(14 + x)(3x + 1) = 0

Reorder the terms:
(14 + x)(1 + 3x) = 0

Multiply (14 + x) * (1 + 3x)
(14(1 + 3x) + x(1 + 3x)) = 0
((1 * 14 + 3x * 14) + x(1 + 3x)) = 0
((14 + 42x) + x(1 + 3x)) = 0
(14 + 42x + (1 * x + 3x * x)) = 0
(14 + 42x + (1x + 3x2)) = 0

Combine like terms: 42x + 1x = 43x

Subproblem 1
Set the factor '(14 + x)' equal to zero and attempt to solve:

Simplifying
14 + x = 0

Solving
14 + x = 0

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

Add '-14' to each side of the equation.
14 + -14 + x = 0 + -14

Combine like terms: 14 + -14 = 0
0 + x = 0 + -14
x = 0 + -14

Combine like terms: 0 + -14 = -14
x = -14

Simplifying
x = -14
Subproblem 2
Set the factor '(1 + 3x)' equal to zero and attempt to solve:

Simplifying
1 + 3x = 0

Solving
1 + 3x = 0

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

Add '-1' to each side of the equation.
1 + -1 + 3x = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 3x = 0 + -1
3x = 0 + -1

Combine like terms: 0 + -1 = -1
3x = -1

Divide each side by '3'.
x = -0.3333333333

Simplifying
x = -0.3333333333
Solution
x = {-14, -0.3333333333}
