Solve for the zeros of the quadratic function f(x) = 9x2 + 6x + 1. write the answer as a fraction.

x = startfraction negative b plus or minus startroot b squared minus 4 a c endroot over 2 a endfraction
x = startfraction negative 6 plus or minus startroot (negative 6) squared minus 4 (9)(1) endroot over 2(9) endfraction
x = startfraction negative 6 plus or minus startroot 36 minus 36 endroot over 18 endfraction
x =
