r^{2} - 4 = 0

r = 2, r = - 2

Solution steps

r^{2} - 4 = 0

Move

4

to the right side

r^{2} = 4

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

r = 4, r = - 4

4 = 2

- 4 = - 2

r = 2, r = - 2

11 + 19 + 27 + (8 n + 3) = n (4 n + 7)

2 (x + 1)^{2} - 35 = 15

12 x^{2} = 24

2 (x + 8)^{2} - 19 = 31

6 - 6 x^{2} - 3 x = 0
