Question

4x^2-3x-7=0 ecuacion cuadratica

Answer 1

Respuesta:

${\sf{ x_{1} = - 1, x_{2} = 1.75 }}$

Explicación paso a paso:

$\boxed{\bf{Tema: \ Ecuaciones \ \ cuadráticas}}$

$\sf4 {x}^{2} - 3x - 7 = 0$

$\sf4 {x}^{2} + 4x - 7x - 7 = 0$

$\sf4x(x + 1) - 7(x + 1) = 0$

$\sf(x + 1)(4x - 7) = 0$

$\sf{x + 1 = 0} \\ \sf{4x - 7 = 0}$

$\sf{x = - 1 \: \: \: } \\ \sf{x = 1,75 }$

$\boxed{\sf{ x_{1} = - 1, x_{2} = 1.75 }}$
