Question

Find the zeros of the function.

f(x) = 9x2 + 6x - 8

Answer 1

finding the zeros means solving for x when f(x)=0

either factor it and solve or use the quadratic equation

Answer 2

it is going to be fraction

Answer 3

just set it equal to zero and solve using the quadratic equation

Answer 4

transformation
\[y=3x\]
\[y ^{2}+2y-8=0\]
\[y=-(2\pm6)/2\]
\[y=-4 \]
\[y=2\]
\[x1=-4/3 \]
\[x2=2/3\]
