Question

(6x^2 - x - 1 )÷( 2x - 1)

Answer 1

Resposta:

$\boxed{\mathtt{3x + 1}}$

Explicação passo-a-passo:

$\displaystyle \\ \mathtt{\frac{6x^2 - x - 1}{2x - 1} =} \\\\\\ \mathtt{\frac{6x^2 - 3x + 2x - 1}{2x - 1} =} \\\\\\ \mathtt{\frac{3x(2x - 1) + 1(2x - 1)}{(2x - 1)} =} \\\\\\ \mathtt{\frac{(2x - 1) \cdot \left [ 3x + 1 \right ]}{(2x - 1)} =} \\\\\\ \boxed{\boxed{\mathtt{3x + 1}}}$
