7 n^{2} = 28

n = 2, n = - 2

Solution steps

7 n^{2} = 28

Divide both sides by

7

n^{2} = 4

For

x^{2} = f (a)

the solutions are

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

n = 4, n = - 4

4 = 2

- 4 = - 2

n = 2, n = - 2

x^{2} + 2 x + 14 = 0

- 4 x^{2} + 5 x + 1 = 0

2 w^{2} - 3 w - 44 = 0

x - 7 = x^{2}

(m + 3) (m - 4) = - 6
