Question

What are the zeros of f(x) 3x^2+9x+12

Answer 1

there are no zeros in f(x)

Explanation:

`f(x)=3x^2+9x+12\\\\f(x)=0\\\\0=3x^2+9x+12\\\\`

to know if the equation has real solutions we have to know if

`b^2-4ac\geq 0`

a=3

b=9

c=12

`9^2-4*3*12\\\\=81-144\\\\=-63`

so there aren't real solutions

hence there aren't any zeros in f(x)
