Ask a Question
Sum of the zeros is (-b/a) which is -3/2
product of the zeros is c/a which is -2/2
Hence two is the answer
Equation of a polynomial whose zeroes are p and q is following --
x2 - (p+q)x + pq = 0
Since we have given that sum of zeroes (p+q) = -3/2
product of zeroes (pq) = -1
x2 - (-3/2)x + (-1) = 0
x2 + (3/2)x + (-1) = 0
2x2 + 3x - 2 = 0
Hence option (2) is correct.
second option as sum of roots is (-b/a) and product of roots is (c/a)
Second option satifies the given condition

I think this answer may help you...
2nd option has the sum of zeroes -3/2 and the product of zeroes - 1
2.
sum of zeroes=-b/a=-3/2
product of zeroes=c/a=-2/2=1
