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 
 
        
             
        
        
        
Lcm of 60 and n = 420
Stated: n <90 and a multiple of 6
420/60 = 7 thus n must be a multiple of 7
 Therefore n =42 or 84
        
             
        
        
        
The value of the digit 8 is 8,000. To find the answer all you have to do is replace all the other numbers with zero. So 28,175 would be 08,000; and because a zero before a number doesn't mean anything, you end up with just 8,000.
