Question

Find the zeros of the function.

f(x) = x^2 + 9x + 20

Answer 1

Can you factor that?

Answer 2

i got -5 and 4

Answer 3

Yeah that's right.

Answer 4

to check you can graph it on the claculator. but factoring is the right way

Answer 5

i did i got -5 and 4 again

Answer 6

check again, im getting -5 and -4

Answer 7

1 sec

Answer 8

-5 and -4 sorry. Not 4.

Answer 9

What @ganeshie8 said.

Answer 10

oh ok i see

Answer 11

thank you !

Answer 12

factoriz it like ?
so -5 and 4 not will add you never 9
this is true that their product is 20 but their sum need adding 9

Answer 13

Answer 14

@babydoll332 check it these numbers please because need adding like sum 9 and like product 20
so hence you will can factoriz it like (x +5)(x+4)=0 and just than you will get the originaly quadratic equation x^2 +9x +20 =0

hope so much that this will help you understanding all right

good luck
