Is 21x2 43x 20 a prime polynomial?
To determine if the polynomial (21x^2 - 43x + 20) is prime, we need to check if it can be factored into the product of two non-trivial polynomials with real coefficients. By applying the discriminant method, we find that the discriminant (b^2 - 4ac) is positive, indicating that it has real roots and can be factored. Therefore, (21x^2 - 43x + 20) is not a prime polynomial.
What does x equal when 21x plus 9 equals 180?
