Solution

Claro, vamos a resolver la ecuación cuadrática 4x228x=374x^2 - 28x = -37 usando la fórmula cuadrática paso a paso.

Primero, reescribimos la ecuación en la forma estándar ax2+bx+c=0ax^2 + bx + c = 0:

4x228x+37=04x^2 - 28x + 37 = 0

Identificamos los coeficientes aa, bb y cc:

a=4a = 4 b=28b = -28 c=37c = 37

La fórmula cuadrática es:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Sustituimos los valores de aa, bb y cc en la fórmula:

x=(28)±(28)24(4)(37)2(4)x = \frac{-(-28) \pm \sqrt{(-28)^2 - 4(4)(37)}}{2(4)}

Simplificamos dentro de la raíz cuadrada:

x=28±7845928x = \frac{28 \pm \sqrt{784 - 592}}{8}

x=28±1928x = \frac{28 \pm \sqrt{192}}{8}

Simplificamos la raíz cuadrada de 192:

192=643=83 \sqrt{192} = \sqrt{64 \cdot 3} = 8\sqrt{3}

Entonces:

x=28±838x = \frac{28 \pm 8\sqrt{3}}{8}

Simplificamos dividiendo cada término por 8:

x=288±838x = \frac{28}{8} \pm \frac{8\sqrt{3}}{8}

x=3.5±3x = 3.5 \pm \sqrt{3}

Por lo tanto, las raíces en su forma más simple son:

x=3.5+3x = 3.5 + \sqrt{3} x=3.53x = 3.5 - \sqrt{3}
