3 x^{2} - x^{2} = 1800

x = 30, x = - 30

Solution steps

3 x^{2} - x^{2} = 1800

Add similar elements:

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

2 x^{2} = 1800

Divide both sides by

2

x^{2} = 900

For

x^{2} = f (a)

the solutions are

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

x = 900, x = - 900

900 = 30

- 900 = - 30

x = 30, x = - 30

x^{2} - 16 x - 2 = 0

x, 3 x^{2} + m x + 3 = 0

x^{2} = 8 x - 12

- 7 x^{2} + 8 x + 8 = 0

4 x^{2} - 3 x - 9 = 0
