u^{2} - 4 = 0

u = 2, u = - 2

Solution steps

u^{2} - 4 = 0

Move

4

to the right side

u^{2} = 4

For

x^{2} = f (a)

the solutions are

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

u = 4, u = - 4

4 = 2

- 4 = - 2

u = 2, u = - 2

4 t^{2} + t + 1 = 0

4 x^{2} = - 6 x

10 b^{2} - 10 = - 141

x (x - 56) = 0

x, y^{2} = 4 x^{2}
