8 x^{2} - 9 = x^{2} - 2

x = 1, x = - 1

Solution steps

8 x^{2} - 9 = x^{2} - 2

Move

9

to the right side

8 x^{2} = x^{2} + 7

Move

x^{2}

to the left side

7 x^{2} = 7

Divide both sides by

7

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

7 x^{2} = 10 x - 3

x^{2} + x - 2 = 4

8 = 2.4 t - 0.1 t^{2}

- 4 x^{2} - 19 x + 5 = 0

y^{2} - 4 y - 45 = 0
