100  121k^2 = 0
k^2 = 100/121
k = ± √(100/121)
k = ± 10/11

From Como: :
k² = 100 / 121
k = ± 10/11

100  121k^2 = 0 can be written as:
100 = 121k^2. So 100/121 = k^2
If we square root both sides we get:
10/11 = k or 0.909 recurring.

From electron1: 100 − 121k² = 0

100 − 121k² = 0
Add 112 k^2 to both sides of this equation.
100 = 112 * k^2
112 * k^2 = 100
Divide both sides by 112.
k^2 = 100 ÷ 112
Let’s take the square root of both sides of this equation.
k = ± (10 ÷ 11)
This is approximately +0.909 or 0.909. I hope this is helpful for you.

100121k^2=0
100/121=(121k^2)/121
k^2=100/121
sqrt(k^2)=sqrt(100/121)
k=10/11

Factor the left side as a difference of squares: 100  121k^2 = (10 + 11k)(10  11k). Then set each factor to 0 and continue.
