2 x^{2} - x^{2} - 1 = 0

x = 1, x = - 1

Solution steps

2 x^{2} - x^{2} - 1 = 0

Move

1

to the right side

2 x^{2} - x^{2} = 1

Add similar elements:

2 x^{2} - x^{2} = x^{2}

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

m^{2} - 5 m - 50 = 0

x, x^{2} + y^{2} = 9

- k^{2} - 8 = 10 k

a^{2} + 3 a - 28 = 0
