Answer:
The sum and product of zeroes are 1 and 1/4, respectively.
Step-by-step explanation:
To determine the zeroes of the quadratic polynomial, let equalize the polynomial to zero and solve in consequence:

By the General Quadratic Formula:


Which means that zeroes are
.
The sum and product of zeroes are, respectively:
