Question

Determine whether the given values of x are zeroes of the given polynomial or not:x^2+6x+5;x=-1;x=-5​

Answer 1

Answer:

Let p(x) = x2 + 6x + 5;

Put x = -1

⇒ p(-1) = (-1)2 + 6(-1) + 5 = 1 - 6 + 5 = 0

Put x = -5

p(-5) = (-5)2 + 6(-5) + 5 = 25 - 30 + 5 = 0

Therefore the given value of x is a zeroes of the given polynomial
