@kiiraa_x3

Answer 19

what do you mean?

Answer 20

general form of quadratic equation ?

Answer 21

like for number 1??

Answer 22

vertex form of quadratic equation is \[\huge\rm y = a (x - h)^2 + k\]
1st) given a should be between 4 and -4 so choose 1 a =1 (easy to deal)

h = birth month
k= birth date
replace variables by their values

Answer 23

My bday is December 9. so, f(x)=1(x-12)^2+9. Right?

Answer 24

now I need help with number 2.

Answer 25

@Nnesha

Answer 26

hello!!!! @Nurali @Nnesha

Answer 27

yes that's right
now (x -12)^2 can be written as (x-12)(x-12)
foil it out
standard form of quadratic equation is \[\huge\rm y = Ax^2 +Bx +C\]

Answer 28

how do I do that

Answer 29

multiply which is in 1st parentheses by 2nd one
