Question

Find the zeroes of quadratic polynomial 2x2-9-3x and verify the relationship between

the zeros and coefficients.​

Answer 1

Step-by-step explanation:

2x^2-3x-9=0

2x^2-6x+3x-9=0

2x(x-3)+3(x-3)

(2x+3)(x-3)=0

x=-3/2

x=3

sum of the zeroes=-b/a

-3/2+3=3/2

3/2=3/2

product of the zeroes=c/a

-3/2×3=-9/2

-9/2=-9/2
