A quadratic polynomial must have zeros, though they may be complex numbers.
A quadratic polynomial with no real zeros is one whose discriminant b2-4ac is negative. Such a polynomial has no special name.
The zeros of a polynomial are the values of the variable for which the polynomial evaluates to zero. These values are also known as the roots or solutions of the polynomial equation. Finding the zeros is essential for understanding the behavior of the polynomial graph, including its intercepts with the x-axis. The zeros can be determined using various methods, such as factoring, the quadratic formula, or numerical techniques.
Try the quadratic formula. X = -b ± (sqrt(b^2-4ac)/2a)
To find the quadratic polynomial whose zeros are 2 and -3, we can use the fact that a polynomial can be expressed in factored form as ( f(x) = a(x - r_1)(x - r_2) ), where ( r_1 ) and ( r_2 ) are the zeros. Here, substituting ( r_1 = 2 ) and ( r_2 = -3 ), we have ( f(x) = a(x - 2)(x + 3) ). Expanding this, we get ( f(x) = a(x^2 + x - 6) ). For simplicity, we can choose ( a = 1 ), giving us the polynomial ( f(x) = x^2 + x - 6 ).

A quadratic polynomial.
It will be a cubic polynomial.
true.
It is a quadratic polynomial.
The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.
