Question
so the two solutions are... (select both answers) 8x² + 14x + 5 = 0 -5/4 1/2 5/4 20/16 8/16 -1/2 no solution ©2020 shore mathletics
Step1: Usar fórmula cuadrática
La fórmula para resolver \( ax^2 + bx + c = 0 \) es \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \). Aquí, \( a = 8 \), \( b = 14 \), \( c = 5 \).
Step2: Calcular discriminante
\( D = b^2 - 4ac = 14^2 - 4(8)(5) = 196 - 160 = 36 \).
Step3: Calcular raíces
\( x = \frac{-14 \pm \sqrt{36}}{2(8)} = \frac{-14 \pm 6}{16} \).
Para \( + \): \( x = \frac{-14 + 6}{16} = \frac{-8}{16} = \frac{-1}{2} \).
Para \( - \): \( x = \frac{-14 - 6}{16} = \frac{-20}{16} = \frac{-5}{4} \).
