Question

find sum of the zeros of the polynomial y^2+9y+20

Answer 1

sum of zeroes = -(coefficient of y)/(coefficient of y^2)

= -9/1
=-9
so sum of zeroes of this polynomial is -9

Answer 2

Answer:

Sum of the zeros of the given polynomial is -9

Step-by-step explanation:

We have been given the equation

$y^2+9y+20$

On comparing this with the standard form of a quadratic expression

$ax^2+bx+c$

$a=1,b=9,c=20$

Now, the formula for the sum of zeros is given by

$-\frac{b}{a}\\\\=-\frac{9}{1}\\\\=-9$

Hence, sum of the zeros of the given polynomial is -9
