Answer:
x = {-6, 0.3333333333}
Step-by-step explanation:
Simplifying
(3x + -1)(x + 6) = 0
Reorder the terms:
(-1 + 3x)(x + 6) = 0
Reorder the terms:
(-1 + 3x)(6 + x) = 0
Multiply (-1 + 3x) * (6 + x)
(-1(6 + x) + 3x * (6 + x)) = 0
((6 * -1 + x * -1) + 3x * (6 + x)) = 0
((-6 + -1x) + 3x * (6 + x)) = 0
(-6 + -1x + (6 * 3x + x * 3x)) = 0
(-6 + -1x + (18x + 3x2)) = 0
Combine like terms: -1x + 18x = 17x
(-6 + 17x + 3x2) = 0
Solving
-6 + 17x + 3x2 = 0
Solving for variable 'x'.
Factor a trinomial.
(-6 + -1x)(1 + -3x) = 0
Subproblem 1
Set the factor '(-6 + -1x)' equal to zero and attempt to solve:
Simplifying
-6 + -1x = 0
Solving
-6 + -1x = 0
Move all terms containing x to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + -1x = 0 + 6
Combine like terms: -6 + 6 = 0
0 + -1x = 0 + 6
-1x = 0 + 6
Combine like terms: 0 + 6 = 6
-1x = 6
Divide each side by '-1'.
x = -6
Simplifying
x = -6
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
