# What are all the zeroes of the function #f(x) = x^2-169#?

##### 3 Answers

The zeroes of f(x) are

#### Explanation:

let f(x) = 0

take square root of both sides

x =

#### Explanation:

#"to find the zeros set "f(x)=0#

#rArrf(x)=x^2-169=0#

#rArrx^2=169#

#color(blue)"take the square root of both sides"#

#rArrx=+-sqrt(169)larrcolor(blue)"note plus or minus"#

#rArrx=+-13larrcolor(blue)"are the zeros"#

#### Explanation:

We call zero of a function to those values of

In our case, we have to resolve

Transposing terms, we have
