x^{2} - 2 = 7

x = 3, x = - 3

Solution steps

x^{2} - 2 = 7

Move

2

to the right side

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

- 5 + 6 x - x^{2}

m^{2} + 2 m + 4 = 0

- x^{2} + 4 x

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

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