Question

if 2 and -1/3 are the zeros of the polynomial 3x² - 2x ² -7x - 2 then find third zero of the polynomial

Answer 1

Answer:

-1

Step-by-step explanation:

let, f(x) = 3x² - 2x ² -7x - 2

given that, two zeroes are

x=2 and x=-1/3 and let third zero is k

then sum of zeroes of the equation is

k+2+(-1/3) = -coefficient of x²/ coefficient of x

k+5/3 = 2/3

k = 2/3 -5/3

k = -3/3

k = -1
