Answer:

[tex]x=-\frac{1}{5} \:or \: x=2 \:or\: x=-6[/tex]

Step-by-step explanation:

Given [tex]f(x)=(5x+1)(4x-8)(x+6)[/tex]

The zeros of the polynomial function are the point where the function f(x) equals zero.

[tex]f(x)=(5x+1)(4x-8)(x+6)=0[/tex]

If abc=0, then a=0 or b=0 or c=0

Therefore:

[tex](5x+1)(4x-8)(x+6)=0 \:means\\5x+1=0 \:or \: 4x-8=0 \:or\: x+6=0\\5x=-1 \:or \: 4x=8 \:or\: x=-6\\x=-\frac{1}{5} \:or \: x=2 \:or\: x=-6[/tex]

Answer:

negative!
