The zeros are the roots, or where the polynomial croses the axis. A polynomial will have 2 roots, that means it has 2 zeros. To find the roots you can graph and look where it crosses the axis, or you can use the quadratic equation. This is also known as the solution.

The zeroes of a polynomial are simply those values of the variables where the polynomial as a whole equals zero.

So, in other words, to find the zeroes of a polynomial, you have to set the whole polynomial equal to zero and then solve for the variable.

For example, if

x^2 - 14x + 49 = 0, you solve for x to find the zero of this polynomial. In this case, the zero is x = 7

The zeroes of a polynomial are the roots of the polynomial.

The roots or the solutions of a polynomial are those values of x that cancels the polynomial.

These values of x could be real or imaginary numbers.

We'll solve an example to emphasize the idea of the root of a polynomial.

P(x) = x^2 - 6x + 5

The roots of the quadratic polynomial are 1 and 5.

We'll substitute x by 1 in the expression of P(x):

P(1) = 1^2 - 6*1 + 5

P(1) = 1-6+5

P(1) = -5+5 = 0

So, the root 1 cancels the polynomial and represents the 1st zero of P(x).

P(5) = 25 - 30 + 5 = 25-25 = 0

So, the root 5 cancels the polynomial and represents the 2nd zero of P(x).

find zero of 3x^3 - 2x^2 - x + 4

this is for quadratic polynomial.

will it be the same for cubic?

pls can u give example
