2 x^{2} - 11 = 87

x = 7, x = - 7

Solution steps

2 x^{2} - 11 = 87

Move

11

to the right side

2 x^{2} = 98

Divide both sides by

2

x^{2} = 49

For

x^{2} = f (a)

the solutions are

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

x = 49, x = - 49

49 = 7

- 49 = - 7

x = 7, x = - 7

- \frac{186}{200} + 0.3

X^{2} = 3 (X - 1)

81 u^{2} v

- \frac{1}{8} - \frac{1}{2}

(- 5)^{2} + 3^{2} = x^{2}
