Question

(X + 2) (X + 3) (X - 1) = (X + 4) (X + 4) (X - 4) + 7
AYUDA POR FAVOR Y SU COMPROBACIÓN.

Answer 1

solucion
(X + 2) (X + 3) (X - 1) = (X + 4) (X + 4) (X - 4) + 7
X^3+4X^2+X-6 = X^3+4X^2-16X-57
x^3-x^3+4x^2-4x^2+x+16x=-57+6
17x=-51
x=-51/17
X = -3


comprobacion
(X + 2) (X + 3) (X - 1) = (X + 4) (X + 4) (X - 4) + 7

(-3+2)(-3+3)(-3-1)=(-3+4)(-3+4)(-3-4)+7

(-1)(0)(-4)=(1)(1)(-7)+7
0=-7+7
0=0

saludos
