Question

9^²-5^-4 find the zeros of the following quadratic polynomial and verify the relationship between the zeros and the coefficients.

Answer 1

Answer:

roots are -4/9,1

Step-by-step explanation:

9x2-5x-4=0

by factorisation,

9x2-9x+4x-4=0

by taking common

9x(x-1)+4(x-1)=0

(9x+4)(x-1)=0

x=-4/9,1

relation between coffectent and zeros is

sum of zeros =-b/a=-4/9+1= -5/9

product of zeros=c/a=-4/9
