Question

A polynomial 5x²+9x+4 ,find the sum of the zeros of polynomial? ​

Answer 1

Step-by-step explanation:

Comparing 5x^2+9x+4 with a,b,c

a=5 ; b=9 ; c=4

Let x and y be the zeros of the polynomial.

Therefore,

x+y=-b/a

= -9/5

Answer 2

Step-by-step explanation:

5x2+9x+4

5x2+5x+4x+4

5x(x+1) +4(x+1)

(5x+4)(x+1)

x=-4/5. x=-1

sum of zeros= -4/5-1

= -9/5
