Question

Verify that whether - 2 and 3 ore
zeroes of the polynomial
polynomial a²-x-6.​

Answer 1

Q.

Verify that whether -2 and 3 one of the zeroes of the polynomial - x² - x - 6

Solution -

polynomial -

p(x) = x² - x - 6

Putting the value of x as -2

p(-2) = (-2)² - (-2) - 6

= 4 + 2 - 6

=> 6 - 6

=> 0

So, -2 is one of the zeroes of p(x)

Putting the value of x as 3

p(3) = 3³ - 3 - 6

= 9 - 3 - 6

= 9 - 9

= 0

So, 3 is also a zero of p(x)

Hence -2 and 3 Both are zeroes of polynomial.

hope it helps.
