Question

A real numbera is called a zero of the polynomial ​

Answer 1

Answer:

The zero of the polynomial is defined as any real value of x, for which the value of the polynomial becomes zero.

A real number k is a zero of a polynomial p(x), if p(k) = 0.

For example P(x)=x

2

−3x−4

then P(−1)=(−1)

2

−(3×−1)−4=0

and P(4)=(4)

2

−(3×4)−4=0

∴ -1 and 4 are called the zeros of the quadratic polynomial x

2

−3x−4

Answer 2

A real numbera is called a zero of the polynomial (×) is a 0.
