Answer

Las soluciones de la ecuación \( x^{2} + 3x - 2 = 0 \) son: \[ x_{1} = \frac{-3 + \sqrt{17}}{2} \quad \text{y} \quad x_{2} = \frac{-3 - \sqrt{17}}{2} \]

Solution

a) Resolver la ecuación cuadrática \( x^{2} + 3x - 2 = 0 \). Para encontrar las soluciones de la ecuación cuadrática \( ax^{2} + bx + c = 0 \), utilizamos la fórmula cuadrática: \[ x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a} \] Identificamos los coeficientes de la ecuación dada: - \( a = 1 \) - \( b = 3 \) - \( c = -2 \) Calculamos el discriminante (\( \Delta \)): \[ \Delta = b^{2} - 4ac = 3^{2} - 4(1)(-2) = 9 + 8 = 17 \] Como el discriminante es positivo (\( \Delta = 17 \)), la ecuación tiene dos soluciones reales y distintas. Aplicamos la fórmula cuadrática: \[ x = \frac{-3 \pm \sqrt{17}}{2 \cdot 1} = \frac{-3 \pm \sqrt{17}}{2} \] Por lo tanto, las soluciones son: \[ x_{1} = \frac{-3 + \sqrt{17}}{2} \quad \text{y} \quad x_{2} = \frac{-3 - \sqrt{17}}{2} \]

Simplify this solution

Beyond the Answer

To solve the quadratic equation \( x^{2}+3x-2=0 \), you can use the quadratic formula: \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \). Here, \( a = 1 \), \( b = 3 \), and \( c = -2 \). Plugging in these values gives you the solutions: \( x = \frac{-3 \pm \sqrt{(3)^2 - 4 \cdot 1 \cdot (-2)}}{2 \cdot 1} \). Simplifying further will lead you to the exact roots of the equation! Understanding how quadratics work is key in many real-world scenarios, like physics and finance. For example, if you want to find the maximum height of a projectile, the height of the projectile can often be modeled by a quadratic equation where you can apply similar solving techniques to ascertain crucial points, such as maximums or intersections!
