¿Raíz de una Ecuación? ¡ Una raíz es el valor en el que la ecuación se hace cero . ¡ Ejemplo : Calcular las raíces de la siguiente ecuación empleando la fórmula general. f 2 ( x ) = x 2 + 4 x + 3 a = 1, b = 4, c = 3 raíz 1 = b + b 2 4 ac 2 a = 4 + 4 2 4(1)(3) 2(1) = 1 raíz 2 = b b 2 4 ac 2 a = 4 4 2 4(1)(3) 2(1) = 3 0 3 ) 3 ( 4 ) 3 ( ) 3 ( 0 3 ) 1 ( 4 ) 1 ( ) 1 ( : 2 2 = + + = = + + = f f ón Comprobaci

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
