Question

find the zeros of the quadratic polynomial 2x^2+5x-3 and verify the relationship between zeros and coefficients

Answer 1

first of all split the middle term and it will be in this form
2x^2+6x-x-3
take common

2x(x+3)-1(x+3)
(2x-1)(x+3)
x=1/2 , -3
verification
let alpha and beta be the zeroes of the polynomial
alpha=1/2 and beta=-3
alpha+beta=-b/a
1/2+(-3)=-5/2
-6+1/2=-5/2
-5/2=RHS
and aplha×beta=c/a
1/2×-3=-3/2
-3/2= RHS
hence, verified
