solve the quadratic equation.\n-2x² + 10x - 11 = 0\nwrite one exact solution in each box. you can add or remove boxes. if there are no real solutions, remove all boxes.

Answer

Explanation:

Step1: Identificar los coeficientes

Para la ecuación -2x² + 10x - 11 = 0, a = -2, b = 10, c = -11.

Step2: Calcular el discriminante

El discriminante $\Delta=b^{2}-4ac$. Sustituyendo los valores: $\Delta=(10)^{2}-4(-2)(-11)=100 - 88 = 12$.

Step3: Aplicar la fórmula cuadrática

La fórmula cuadrática es $x=\frac{-b\pm\sqrt{\Delta}}{2a}$. Sustituyendo a = -2, b = 10 y $\Delta = 12$: $x=\frac{-10\pm\sqrt{12}}{2(-2)}=\frac{-10\pm2\sqrt{3}}{-4}=\frac{5\pm\sqrt{3}}{2}$.

Answer:

$x=\frac{5 + \sqrt{3}}{2}$, $x=\frac{5 - \sqrt{3}}{2}$
