Question

If x = 1/3 is a zero of the Polynomial p(x) = 27x3 - ax2 - x + 3then find the value of ‘a’ 3

Answer 1

Answer:

a = 33

Step-by-step explanation:

p(x) = 27x³ - ax² - x + 3

x = 1/3 is a zero of p(x)

then , p(x) = 0

put x = 1/3 in p(x)

p(1/3) = 27(1/3)³ - a(1/3)² - 1/3 + 3

= 27(1/27) - a(1/9) - 1/3 + 3

= 1 - a/9 - 1/3 + 3

= (3 - 1 + 9)/3 - a/9

= (2 + 9)/3 - a/9

= 11/3 - a/9 = 0

= 11/3 = a/9

= 11/3 × 9 = a

= 11 × 3 = a

= 33 = a
