Question

Write an example of a biquadratic polynomial​

Answer 1

Answer:

p(1)=2+1-2-1=0. Therefore, the zero of the polynomial is 1 and the factor is x-1. For a biquadratic polynomial, p(x)=x4+2x3-2x-1, the first two zeroes are found by trial and error method. Therefore, the factor is (x-1).

Answer 2

Answer:

For example, p(x)=2x3+x2-2x-1. So, we now put different values of x to find the zero of the polynomial. p(1)=2+1-2-1=0. ... For a biquadratic polynomial, p(x)=x4+2x3-2x-1, the first two zeroes are found by trial and error method.
