Answer:

1, -6

Step-by-step explanation:

Since there are alike numbers, add them together.

4x+x= 5x

Now the function is: f(x)= [tex]x^{2}[/tex]+5x-6

The function is in  [tex]a^{2}[/tex]+bx+c form.

So find the factors of a x c = b.

Factors of -6(a) that fits (b)5 is (-1,6).

Then you just factor it:

f(x)= [tex]x^{2}[/tex]+5x-6

(x-1)(x+6)

x-1= 0  x+6=0

 +1 +1     -6  -6

x=1      x=-6

Those are the real zeroes: 1, -6
