Question

1) f(x) = 3x2+ 5x -2  a) Write an equation that can be used to find the zeros of the function.  b) What are the zeros of the function?

Ladonna · Answer

Here you go:

a) f(x)= (3x-1)(x+2)
This is factoring. It helps you find the zeros if you set this equal to zero. You can clearly identify what the zeros are.

b) (3x-1)(x+2)=0
x=1/3, x=-2

Plug those back into the equation to see if they work. In this case they do so those are your answers.
