3 x^{2} - 4 x = 15

x = - \frac{5}{3} or x = 3

Solution steps

3 x^{2} - 4 x = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x^{2} - 4 x = - 15 or 3 x^{2} - 4 x = 15

3 x^{2} - 4 x = - 15 or 3 x^{2} - 4 x = 15

No Solution or (x = - \frac{5}{3} or x = 3)

x = - \frac{5}{3} or x = 3

25 n^{2} + 10 n + 1

15 b^{3} + 24 b^{2} + 35 b + 56

- \frac{2}{3} + \frac{5}{6}

r^{2} = 5 r - 1

6 x + 3 = 8 x - 5
