\( (3x+5)^2 = (2x-1)^2 \)
\( 9x^2 + 30x + 25 = 4x^2 - 4x + 1 \)
\( 9x^2 - 4x^2 + 30x + 4x + 25 - 1 = 0 \)
\( 5x^2 + 34x + 24 = 0 \)
\[ D = b^2 - 4ac = 34^2 - 4 \cdot 5 \cdot 24 = 1156 - 480 = 676 \]
\[ x_1 = \frac{-b + \sqrt{D}}{2a} = \frac{-34 + \sqrt{676}}{2 \cdot 5} = \frac{-34 + 26}{10} = \frac{-8}{10} = -0.8 \]
\[ x_2 = \frac{-b - \sqrt{D}}{2a} = \frac{-34 - \sqrt{676}}{2 \cdot 5} = \frac{-34 - 26}{10} = \frac{-60}{10} = -6 \]
Ответ: x1 = -0.8, x2 = -6.
