λ^{2} - 4 = 0

λ = 2, λ = - 2

Solution steps

λ^{2} - 4 = 0

Move

4

to the right side

λ^{2} = 4

For

x^{2} = f (a)

the solutions are

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

λ = 4, λ = - 4

4 = 2

- 4 = - 2

λ = 2, λ = - 2

3 x^{2} - 8 x + 5 = 0

4 x (x - 6) = - 9

3 x^{2} + 26 x + 47 = 7

2 x^{2} + 28 = 100

x^{2} - 20 x + 118 = 0
