57 = 30 - x^{2}

x = 33 i, x = - 33 i

Solution steps

57 = 30 - x^{2}

Switch sides

30 - x^{2} = 57

Move

30

to the right side

- x^{2} = 27

Divide both sides by

- 1

x^{2} = - 27

For

x^{2} = f (a)

the solutions are

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

x = - 27, x = - - 27

- 27 = 33 i

- - 27 = - 33 i

x = 33 i, x = - 33 i

7 x^{2} + 20 x + 12 = 0

7 x^{2} - 2 b x - 7 = 0

16 = - 6 t + t^{2}

4 y = 7 y (y - 1) - 3 (y - 1)

x^{2} - 12 x - 108 = 0
