Find a polynomial f (x) satisfying the equation x f'' (x) + 2 f (x) = 9 x^2. What is the sum of the polynomials (7x^3 - 4x2) and (2x^3 - 4x2)? How do you factor 4x^2 + 25? How do you factor x^3 - 4x^2 - 7x = -10?
The properties of a polynomial are:They must be a sum of monomials (nxm).The exponents of a polynomial must be integers. The exponents must be positive. They must be written in descending order taking into account the exponent. The degree of the exponent depends on the greates...
If p/q is a rational zero of a polynomial P(x) with integral coefficients,then p is a factor of a0 (the constant term) and q is a factor of aN (the leading coefficient).除此以外,我只知道这是一个叫做Rational zero(root) theorem 的定理。
These are equations in which the variables are affected bytrigonometric functions. Cos 2x= 1+Sin 4x is a trigonometric equation. 5. Polynomial equations A polynomial equation is one which takes away the highest exponent limit. Here all the ‘x’s are numbers and the equation consists of severa...
