Solution for f(0)=9x^2-6x equation:


Simplifying
f(0) = 9x2 + -6x

Reorder the terms for easier multiplication:
0f = 9x2 + -6x

Anything times zero is zero.
0f = 9x2 + -6x

Reorder the terms:
0 = -6x + 9x2

Solving
0 = -6x + 9x2

Solving for variable 'x'.
Remove the zero:
6x + -9x2 = -6x + 9x2 + 6x + -9x2

Reorder the terms:
6x + -9x2 = -6x + 6x + 9x2 + -9x2

Combine like terms: -6x + 6x = 0
6x + -9x2 = 0 + 9x2 + -9x2
6x + -9x2 = 9x2 + -9x2

6x + -9x2 = 0

Factor out the Greatest Common Factor (GCF), '3x'.
3x(2 + -3x) = 0

Ignore the factor 3.

Subproblem 1

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

Subproblem 2

Set the factor '(2 + -3x)' equal to zero and attempt to solve: Simplifying 2 + -3x = 0 Solving 2 + -3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -3x = 0 + -2 -3x = 0 + -2 Combine like terms: 0 + -2 = -2 -3x = -2 Divide each side by '-3'. x = 0.6666666667 Simplifying x = 0.6666666667

Solution

x = {0, 0.6666666667}
