a^{2} = 400

a = 20, a = - 20

Solution steps

a^{2} = 400

For

x^{2} = f (a)

the solutions are

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

a = 400, a = - 400

400 = 20

- 400 = - 20

a = 20, a = - 20

4 \geq 4 v - 4

3 x^{2} + 36 x + 81 = 0

∣ 2 (x - 1) + 4 ∣ \leq 26

x^{2} = x + 132

5 x + \frac{5}{3} \leq - 2 x - \frac{2}{3}
