Which statements are true when solving x^2=81

x

2

=

81

can be written as

x

2

−

81

=

0

by property ,

a

2

−

b

2

=

(

a

+

b

)

(

a

−

b

)

The expression becomes

x

2

−

(

9

)

2

=

0

(

x

−

9

)

(

x

+

9

)

=

0

equating each of the terms with zero we obtain the solution

x

−

9

=

0

and

x

+

9

=

0

the solutions are

x

=

9

or

x

=

−

9

Step-by-step explanation:

A) Take the square root of both sides to solve

E) x = ±9
