7 + 2 n^{2} = 135

n = 8, n = - 8

Solution steps

7 + 2 n^{2} = 135

Move

7

to the right side

2 n^{2} = 128

Divide both sides by

2

n^{2} = 64

For

x^{2} = f (a)

the solutions are

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

n = 64, n = - 64

64 = 8

- 64 = - 8

n = 8, n = - 8

- 3 x^{2} + 2 x + 4 = - x - 3

- 4 m^{2} + 2 m - 11 = - 5 m^{2}

- 12 x^{2} - 92 x - 56 = 0

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

3 x^{2} - (2 m + 12) x + 216 = 0
