Question

product of zeros of the polynomial x3-2x2+5x+6 is A (6 )B( -6) C (5 )D (2)​

Answer 1

answer : option (B) - 6

polynomial is x³ - 2x² + 5x + 6

so, product of zeros of the polynomial = - constant/coefficient of x³

= -6/1 = -6

[ concept : if any polynomial, ax³ + bx² + cx + d is given then,

sum of zeros = - coefficient of x²/coefficient of x³ = -b/a

sum of products of two consecutive zeros = coefficient of x/coefficient of x³ = c/a

product of zeros = -constant/coefficient of x³ = -d/a ]
