Question

ecuaciones de segundo grado: 4ײ-3×+1=0

Answer 1

$4 x^{2} -3x-1=0$

Resolvemos con la formula general

$X= \frac{3 \frac{+}{} \sqrt{-3^{2}-4*4*-1 } }{2*4}$

$X= \frac{3 \frac{+}{} \sqrt{9+16} }{8}$

$X= \frac{3 \frac{+}{} \sqrt{25} }{8}$

$X= \frac{3 \frac{+}{}5 }{8}$

Tenemos

$X_{1} = \frac{3+5}{8} = \frac{8}{8} = 1$

$X_{2} = \frac{3-5}{8} = - \frac{2}{8} = -\frac{1}{4}$
