Without using a calculator, determine the number of real zeros of the function fox) = x2 + 4x + x - 6.

1, -6

Step-by-step explanation:

Since there are alike numbers, add them together.

4x+x= 5x

Now the function is: f(x)= +5x-6

The function is in  +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)= +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

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
