Question

Check 3 and -2 are the zeros
of the polynomial x²-x-6 or
not​

Answer 1

Required Answer:-

Question:

• Check if 3 and -2 are the zeros of the polynomial x² - x - 6 or not.

Solution:

We have,

➡ p(x) = x² - x - 6

Putting x = 3,we get,

p(3) = (3)² - 3 - 6

= 9 - 9

= 0

Therefore, 3 is a zero of this polynomial.

Again,

Putting x = -2, we get,

p(-2) = (-2)² - (-2) - 6

= 4 + 2 - 6

= 6 - 6

= 0

Therefore, -2 is also a zero of this polynomial.

★ Hence, 3 and -2 are the zeros of the given polynomial.
