Step-by-step explanation:
6x²-9x+2x-3
3x(2x-3)+1(2x-3)
(2x-3)(3x+1)
2x-3=0 or 3x+1=0
x=3/2 or x= -1/3
Relationship between the zeroes and coefficients
1. sum of zeroes = alpha+ beta
-b/a = 3/2+(-1/3)
-(-7)/6= 3/2-1/3
7/6= 9-2/6
7/6= 7/6
2. product of zeroes = (alpha)(beta)
c/a = (3/2)(-1/3)
-3/6 = -1/2
-1/2= -1/2

Step-by-step explanation:
- since we know that if the solution of ax^2+bx+c=0 is x1 and x2 then x1+ x2=-b/a
- and products of zeroes(root) =c/a
6x^2-7x-3=0
upon Factorization
(2x-3)(3x+1)=0
then zeroes are x1= 3/2, x2=-1/3
since x1+x2=-b/a
then -b/a=7/6 and by above solution we also get x1+x2=7/6
and also x1*x2=-3/6=3/2*-1/3=-1/2
