Question

for quadratic polynomial given one zero how to another zero

Answer 1

Hi friend!!

Let the polynomial be ax²+bx+c

This equation has two zeroes.
Let the two zeroes be p and q

Method-1;

We know that,
Sum of zeroes = -x coefficient/x² coefficient
p+q = -b/a

Thus, you can find another zero.

Method-2;

We also know that,
Product of zeroes = constant/x² coefficient
pq = c/a


By substituting the values of given zero, and coefficients, you can find another zero.
