- 2 x^{2} - 9 = - 107

x = 7, x = - 7

Solution steps

- 2 x^{2} - 9 = - 107

Move

9

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

64 x^{2} + 16 x + 1

\frac{2 - 2 i ^{3}}{3 - i ^{5}} + \frac{- 2 i}{1 - i}

(2 x + 2)^{2} + (4 x)^{2} < (5 x + 1)^{2}

6 (n + 3) + 2 > 3 (n + 2) + 6

0.4 r - 0.13 - 0.7 r = 3 r - 5.74
