A 7th degree polynomial.
x = ? 42 = x squared minus x

Depending on the missing operational sign, that would be 2(x plus or minus 8)
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
which of the following is a factor of x2 - 5x - 6
This has a degree of 2.
4x2 - 4 is a polynomial of degree two.
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.
(x + 1)(x - 1)
Yes. If the coefficient of the third degree terms in one polynomial are the additive inverses (minus numbers) of the coefficient of the corresponding terms in the second polynomial. Eg: 3x3 + 2x2 + 5 and -3x3 + x - 7 add to give 2x2 + x - 2
Yes, it is a linear polynomial.
F(x) = 15x2 - 2.5 + 3 That's a quadratic or 2nd degree polynomial in x.
x = ? 42 = x squared minus x
Yes.
2x^3 - 3x^2 + 4x - 3
(3x + 1)(x - 5)
2(4m-3)
