What are the solutions to the equation 3(x – 4)(x + 5) = 0?
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 \(3(x - 4)(x + 5) = 0\)
To solve for x we set each factor =0 and solve for x
\(3(x-4)=0\)
divide each term by 3
\((x-4)=0\)
Add 4 on both sides
\(x=4\)
\(x+5=0\)
Subtract 5 on both sides
\(x=-5\)
So x values are -5 and 4
