Question

Resuelve cada una de las siguientes ecuaciones, apli-cando el factor común monomio.a. x2 – 8x = 0b. x2 + 2x = 0c. x2 – 7x = 0d. x2 + 3x = 0e. x2 – 12x = 0f.x2 – 15x = 0

Answer 1

Respuesta:

a. x2 – 8x = 0

factor comun x:

x ( x - 8 ) = 0

x = 0

x = 8

b. x2 + 2x = 0

factor comun x:

x ( x + 2 )= 0

x =0

x = -2

c. x2 – 7x = 0

factor comun x:

x ( x - 7 ) = 0

x = 0

x = 7

d. x2 + 3x = 0

x ( x + 3) = 0

x = 0

x = -3

e. x2 – 12x = 0

x ( x -12)=0

x=0

x=12

f.x2 – 15x = 0

x(x-15)=0

x=0

x=15
