|x^2-2*x-3|=0

x^{2} - 2 \cdot x - 3 = 0

x = - 1 or x = 3

Solution steps

x^{2} - 2 x - 3 = 0

Apply absolute rule: If

∣ u ∣ = 0

then

u = 0

x^{2} - 2 x - 3 = 0

x^{2} - 2 x - 3 = 0 : x = 3, x = - 1

x = - 1 or x = 3

(r t)^{12}

\frac{x - 1}{3} + \frac{2 - x}{5} = 1

4 x^{2} + 3 = - 7 x

4 x^{2} - 9 x

a = 60000 (1 + \frac{0.06}{4})^{4 \cdot 5}
