Question

If p(x) = 2x^2 + 7x +0 is a quadratic polynomial, then what will be the
product of the zeroes ?
(a)10 (b) 7 (c) 1(d) 5​

Answer 1

Answer:

b²-4ac = 7² - 4×2×0 = 49 - 0 = 49

∴ x= -b √b²-4ac/ 2a

= -7 √49 / 4

=-7 ± 7 / 4

CASE I

⇒ -7 + 7 /4 = 0/4 = 0

CASE II

⇒ -7-7 / 4 = -14/4 = -7/2

∴ Product of the zeroes will be = -7/2 × 0 = 0

THE OPTIONS ARE INCORRECT. 0 IS THE PRODUCT, PLEASE CHECK YOUR QUESTION ONCE AGAIN :)
