Answer 2

Respuesta:

$\boxed{\mathbf{-4x^{2}+3x+1=0;x_{1}=-\frac{1}{4};x_{2}=1}}$

Explicación paso a paso:

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

Identificamos los coeficientes a,b y c

$a=-4\,,b=3\,,c=1$

Aplicamos la fórmula general:

$x=\frac{-b\pm\sqrt{b^{2}-4ac}}--{2a}\\\\x=\frac{-3\pm\sqrt{(3)^{2}-4(-4)(1)}}{2(-4)}\\\\x=\frac{-3\pm\sqrt{9+16}}{-8}\\\\x=\frac{-3\pm\sqrt{25}}{-8}\\\\x=\frac{-3\pm5}{-8}\\\\x_{1}=\frac{-3+5}{-8}=-\frac{2}{-8}=-\frac{1}{4}\\\\x_{2}=\frac{-3-5}{-8}=\frac{-8}{-8}=1$
