Question

the product of two zeros of p(x) =x3-5x2-11x+12 is 3 then third zero is
​

Answer 1

Answer:

given

p(x) = x³ - 5x² - 11x + 12

let the third root be R

so product of all three roots = 3*R = 3R

now,

we know

product of roots = -constant term/ coefficient of x³

=> 3R = 12

=> R = 12/3 = 4

so , R = 4

thus the third root is 4.
