21 - 2 x^{2} = - 51

x = 6, x = - 6

Solution steps

21 - 2 x^{2} = - 51

Move

21

to the right side

- 2 x^{2} = - 72

Divide both sides by

- 2

x^{2} = 36

For

x^{2} = f (a)

the solutions are

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

x = 36, x = - 36

36 = 6

- 36 = - 6

x = 6, x = - 6

x (x + 36) = 5152

x^{2} = 7^{2} + 5^{2}

2 X^{2} - X + 3 = 0

x, x^{2} + y^{2} - 2 h x = 0

n^{2} - 3 n - 18 = 0
