Solution

Claro, vamos a resolver la ecuación paso a paso.

La ecuación dada es: 6x2+6x13=0 6x^2 + 6x - 13 = 0

Para resolver esta ecuación cuadrática, utilizaremos la fórmula cuadrática: x=b±b24ac2a x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

En esta ecuación, los coeficientes son: a=6 a = 6 b=6 b = 6 c=13 c = -13

Primero, calculamos el discriminante (Δ \Delta ): Δ=b24ac \Delta = b^2 - 4ac Δ=624(6)(13) \Delta = 6^2 - 4(6)(-13) Δ=36+312 \Delta = 36 + 312 Δ=348 \Delta = 348

Ahora, aplicamos la fórmula cuadrática: x=b±Δ2a x = \frac{-b \pm \sqrt{\Delta}}{2a} x=6±34812 x = \frac{-6 \pm \sqrt{348}}{12}

Calculamos la raíz cuadrada de 348: 34818.7 \sqrt{348} \approx 18.7

Entonces, tenemos dos soluciones: x1=6+18.712 x_1 = \frac{-6 + 18.7}{12} x1=12.712 x_1 = \frac{12.7}{12} x11.1 x_1 \approx 1.1

x2=618.712 x_2 = \frac{-6 - 18.7}{12} x2=24.712 x_2 = \frac{-24.7}{12} x22.1 x_2 \approx -2.1

Por lo tanto, las soluciones de la ecuación 6x2+6x13=0 6x^2 + 6x - 13 = 0 son aproximadamente: x11.1 x_1 \approx 1.1 x22.1 x_2 \approx -2.1
