True.
3x^4 + 4x^3 - 3x^4 + 5x + 1
= 4x^3 + 5x + 1
True Yes. Although the term 'quad' stands for four, a quadratic equation is a polynomial of second degree.
False. It has to be either "- 24x" or "+ 36". These would factor as (3x - 4)2 and (3x - 6)2 respectively.
True
If the coefficients of a polynomial of degree three are real it MUST have a real zero. In the following, asymptotic values are assumed as being attained for brevity: If the coeeff of x3 is positive, the value of the polynomial goes from minus infinity to plus infinity as x goes from minus infinity to plus infinity. The reverse is true if the coefficient of x3 is negative. Since all polynomials are continuous functions, the polynomial must cross the x axis at some point. That's your root.
Is |-8|+|3|=|-8+3| true or false?
true.
true!
True Yes. Although the term 'quad' stands for four, a quadratic equation is a polynomial of second degree.
False. The height of the degree does not really matter in this case. There just have to be other monomials in the problem to be considered a polynomial. "Poly" means many.
