Question

5. The product of the zeroes of quadratic polynomial x2 + 7x + 10 is
(A) 1 (B) 7 (C) 10
(D) -10​

Answer 1

Answer:

x2 + 7x + 10

method 1st

x2 + (2+5)x + 10

x2 + 2x+5x + 10

x(x + 2)+5(x + 2)

(x+5 )(x+2)

x+5 = 0 , x+2 = 0

x= -5 , x= -2

product of the zeros = -5×-2 = 10

method 2nd

x2 + 7x + 10   (i)

ax2 +bx + c   (ii)

comparing (i) and (ii)

a=1,b=7 ,c=10

product of zeros = c/a = 10/1 =10

c) Is a correct option
