9 x^{2} + 4 = 724

x = 45, x = - 45

Solution steps

9 x^{2} + 4 = 724

Move

4

to the right side

9 x^{2} = 720

Divide both sides by

9

x^{2} = 80

For

x^{2} = f (a)

the solutions are

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

x = 80, x = - 80

80 = 45

- 80 = - 45

x = 45, x = - 45

x^{2} - 2 x - 17 = 0

0.35 x - 4.8 < 5.2 - 0.9 x

3 + x = 7

∣ 3 x ∣ > - 2

7 (x + 1) = 5 - 2 (7 x + 6)
