(x^2-9)/(3-x)=0

\frac{x ^{2} - 9}{3 - x} = 0

x = - 3

Solution steps

\frac{x ^{2} - 9}{3 - x} = 0

Simplify

\frac{x ^{2} - 9}{3 - x} : - x - 3

- x - 3 = 0

Move

3

to the right side

- x = 3

Divide both sides by

- 1

x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 3

Combine undefined points with solutions:

x = - 3

\frac{18}{x} = \frac{6}{10}

50 = \frac{a}{( 7.906 - h )} + k

\frac{x + 3}{x + 2} = \frac{4}{5}

- 3 = \frac{1}{4 c}

\frac{1}{x} = 5 + \frac{1}{x ^{2} + x}
