Question

Find the sum of the zeros of the quadratic polynomial 3x² + 2x - 5 .​

Answer 1

Answer:

-2/3

Step-by-step explanation:

3x^2 + 2x - 5

3x^2+5x-3x-5  (by splitting the middle term)

x(3x + 5) -1 (3x+5) ( taking common )

(x-1)(3x+5)

by, putting both equals to zero

x-1=0

x=1 (is one zero of the given polynomial)

now,

3x+5=0

3x=-5

x=-5/3 (is second zero of the polynomial )

now in question we are asked the sum of zeros which is

=> -5/3+1

=> -5+3/3

=> -2/3
