Respuesta :

first you distribute the 3
(3x-12) (x+5)=0
then you set each equation equal to zero
3x-12=0 & x+5=0
then you solve for x
x =4, -5

Answer:

-5, 4

Step-by-step explanation:

the solutions to the equation [tex]3(x - 4)(x + 5) = 0[/tex]

To solve for x we set each factor =0 and solve for x

[tex]3(x-4)=0[/tex]

divide each term by 3

[tex](x-4)=0[/tex]

Add 4 on both sides

[tex]x=4[/tex]

[tex]x+5=0[/tex]

Subtract 5 on both sides

[tex]x=-5[/tex]

So x values are -5 and 4
