3 x^{2} - 1200 = 0

x = 20, x = - 20

Solution steps

3 x^{2} - 1200 = 0

Move

1200

to the right side

3 x^{2} = 1200

Divide both sides by

3

x^{2} = 400

For

x^{2} = f (a)

the solutions are

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

x = 400, x = - 400

400 = 20

- 400 = - 20

x = 20, x = - 20

5 x^{2} = 2 x + 7

5 x^{2} - 16 x - 3 = 0

- x^{2} - 4 x + 7

- x^{2} - 4 x + 4

(2 x + 5) (x - 1) = 0
