Question

(x+1) | (3x+11)
(2x-1) | (4x+5)​
|=divide​

Answer 1

Explicație pas cu pas:

$\frac{3x + 11}{x + 1} = 3 + \frac{8}{x + 1} \\ x + 1 \: divide \: 8 \\ x + 1 = 1 \: \: \: x = 0 \\ x + 1 = 2 \: \: x = 1 \\ x + 1 = 4 \: \: x = 3 \\ x + 1 = 8 \: \: x = 7 \\ \\ \\ \frac{4x + 5}{2x - 1} = 2 + \frac{7}{2x - 1} \\ 2x - 1 \: divide \: 7 \\ 2x - 1 = 1 \: \: 2x = 2 \: \: x = 1 \\ 2x - 1 = 7 \: \: 2x = 8 \: \: x = 4$
