ME AJUDE NESSA QUESTÃO POR FAVOR

Answer 1

Resposta:

$a)3 {x}^{2} = x \\3 {x}^{2} - x = 0 \\ x \times (3x - 1) = 0 \\ {x}^{i} = 0 \\ {x}^{ii} = \frac{1}{3} \\ b)2 {x}^{2} - 4x = 0 \\ x \times (2x - 4 ) = 0 \\ {x}^{i} = 0 \\ {x}^{ii} = 2\\ c) {x}^{2} - 5x = 0 \\ x \times (x - 5) = 0 \\ {x}^{i} = 0 \\ {x}^{ii} = 5 \\d) 3 {x}^{2} - 12x = 0 \\ x \times (3x - 12) = 0 \\ {x}^{i} = 0 \\ {x}^{ii} = 4$
