Question

Polynomial
1. The quadratic polynomial whose sum of zeroes is 3 and product of zeroes is -2 is:
(a) x2 + 3x - 2 (b) x2 - 2x +3 (c) x²-3x + 2 (d) x2 -3x - 2
​

Answer 1

Answer:

c

Step-by-step explanation:

x²-3x+2= x²-x-2x+2=x(x-1)-2(x-1)=(x-1)(x-2)

thus, roots(i.e. zeroes) of this quadratic eq are +1 and +2

Product of +1 & +2=2

Sum of +1&+2= 3

Answer 2

Answer:

Step-by-step explanation:

x²-3x+2= x²-x-2x+2=x(x-1)-2(x-1)=(x-1)(x-2)

thus, roots(i.e. zeroes) of this quadratic eq are +1 and +2

Product of +1 & +2=2

Sum of +1&+2= 3

C is right
