Question

If one zero of the quadratic polynomial 2x square + 3x + p is 3. Find p and the another zero

Answer 1

Answer:

2x+3x+p =0

p=-3x-2x

p= -5x

-5x=p

x=p

-5

Answer 2

Answer:

p=-27 Another zero is -9/2

Step-by-step explanation:

let m&n are the zeroes of this polygon

m=3

P(x)=2x^2+3x+p

if 3is zero of this quadratic polynomial

2(3)^2+3×(3)+p=0

18+9+p=0

27+p=0

p=-27

m+n=-3/2

3+n=-3/2

n=-9/2
