Answer:
(x+6)(x−6)=0
x=-6 or x=6
Step-by-step explanation:
X^2 - 36 = 0
Solve by Square Root
add 36 both sides
x^2−36+36=0+36
x^2=36
square root
x=±√36
x=6 or x=−6
You can do that or for 2nd option
Solve by factoring
x^2-36=0
(x+6)(x−6)=0
Set factors equal to 0
x+6=0 or x−6=0
x=-6 or x=6
PLEASE NOTE: 36 is the square of 6
and
x2 is the square of x1

Answer:
$704.73
Step-by-step explanation:
Take the original amount of money in the account minus $345.69 for the dentist.
$1,142 - $345.69 = $796.31
Now take this amount minus $15.89 for groceries
$796.31 - $15.89 = $780.42
Finally, take this amount minus $75.69 for the electric bill
$780.42 - $75.69 = $704.73
