Solve by factoring.
A^2 – 121 = 0
(A-11)(A+11) = 0
A = 11 or A = -11
==============================
Solve by factoring.
X^2 – 2x – 24 = 0
(x-6)(x+4) = 0
x = 6 or x = -4
==============================
Solve by using the even-root property.
X^2 = 20
X = 2sqrt(5) or x = -2sqrt(5)
========================================
