Given that,

An equation :

To find,

The zeros of the above function.

Solution,

To find zero, put y = 0

So, the zeros of the above quadratic equation is -4 and -5.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

i can answer this if i have the answer choices
