Answer:

x=-\frac{1}{5}  \:or \: x=2 \:or\: x=-6

Step-by-step explanation:

Given f(x)=(5x+1)(4x-8)(x+6)

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

f(x)=(5x+1)(4x-8)(x+6)=0

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

Therefore:

(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

Decide whether the statement is true or false. If it is​ false, explain why. The union of the solution sets of 4xplus5equals13​,
postnew [5]

The given statement is false because it isn't an empty set!

<u>Step-by-step explanation:</u>

We have following sets of inequalities:

4x+5=13\\4x+5>13\\4x+5

From 4x+5=13 we get ,

4x = 8 \\x=2

Therefore solution set is x=2.

Now, for 4x+5>13 we get ,  

4x+5>13 \\4x>8\\x>2

Therefore solution set is x>2.

For 4x+5 we get ,

4x+5

Therefore solution set is x<2.

Now, the union of x=2, x<2 & x>2 is  -∞<x<∞. i.e. all possible values of x. And so above statement is false because it isn't an empty set!
