Question

the quadratic polynomial whose sum of the zeros is 3 and product is -2 is

Answer 1

Answer:

x^2-3x-2

Step-by-step explanation:

Let the quadratic equation be =ax^2+bx+c

Given,sum of zeroes=3 and product of zeroes=-2

sum of zeroes=- b/a

-b/a=3

i.e b/a=-3_1

product of zeroes=c/a

i.e c/a=-2_2

we have to take l.c.m. of 1and1=1

put the value of a=1 in eq.1and2

b=-3 and c=-2

Thus, the quadratic equation will be x^2-3x-2.
