(x^2-16)/(x-4)=0

\frac{x ^{2} - 16}{x - 4} = 0

x = - 4

Solution steps

\frac{x ^{2} - 16}{x - 4} = 0

Simplify

\frac{x ^{2} - 16}{x - 4} : x + 4

x + 4 = 0

Move

4

to the right side

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 4

Combine undefined points with solutions:

x = - 4

\frac{x}{x - 3} = \frac{3}{x - 3} + 3

y, y^{- 2} = x - 1

z - 4 = 5 z^{- 1}

a = \frac{2 d}{t ^{2}}

1000 = \frac{1}{x ^{2} - 1}
