Question

3(x+2)(x+3)=60 ayuda por favor​

Answer 1

Respuesta:

X1 = 2

X2 = - 7

Explicación paso a paso:

3(x+2)(x+3)=60

(3x+6)(x+3)=60

3x^2 + 9x + 6x + 18 = 60

3x^2 + 15x - 42 = 0

X = [- 15 +- raiz(225 + 504)] / 6

X = [- 15 +- raiz(729)] / 6

X = (- 15 +- 27) / 6

X1 = (-15 + 27) / 6 = 12 / 6 = 2

X2 = (-15 - 27)/6 = - 42 / 6 = -7
