Question

Find the zeroes in F(x) = 3x^2 + 9x + 12

Answer 1

F(x) = 3x^2 + 9x + 12,
The zeroes of the function are the value of x when F(x)=0.

3x²+ 9x + 12 = 0 (divide all equation by 3)
x²+3x+4 =0

a=1, b=3, c=4


`D= b^(2)-4ac=3^(2) -4*1*4=9-16= -4 \ \textless \ 0, so no real solutions.`

There are no real zeros for this function.
