Question

Qual o resultado de
4x+1=2 sobre x

Answer 1

4x + 1 = 2/x

(4x+1)x = 2

(4x+1)x - 2 =0

4x² + x - 2 = 0

$x=\frac{-1\pm \sqrt{1^2-4\times 4 \times (-2)} }{2 \times 4}$

$x = \frac{-1 \pm \sqrt{1+32} }{8}$

$x=\frac{-1\pm \sqrt{33} }{8}$

$x_1 = \frac{-1+\sqrt{33} }{8}\\x_2= \frac{-1-\sqrt{33} }{8}$
