Question

Решите уравнение (2x − 1)2 − 2(х − 3) = (х + 5)(4х − 3).

Answer 1

(2x-1)²-2(x-3)=(x+5)(4x-3);

4x²-4x+1-2x+6=4x²+20x-3x-15;

23x=22

x=22/23

Answer 2

$4{x}^{2} - 4x + 1 - 2x + 6 = 4 {x}^{2} - 3x + 20x - 15 \\ \\ - 4x + 1 - 2x + 6 = - 3x + 20x - 15 \\ \\ - 6x + 7 = 17x - 15 \\ \\ - 6x - 17x = - 15 - 7 \\ \\ - 23x = - 22 \\ \\ x = \frac{22}{23}$
