Which expression is equivalent to $$\left(2x-3\right)^2-3.5x^2\left(2x-5\right)+6x\left(2.5x^2-x+3.1\right)$$ ?

The equivalent expression is $$8x^3 + 15.5x^2 + 6.6x + 9$$ .

Find the linear factors of $$h(x) = x^4 + 2x^3 - 3x^2 - 8x - 4$$ .

The linear factors are $$h(x) = (x + 2)(x - 2)(x + 1)^2$$ .

What is the Remainder Theorem?

The Remainder Theorem states that the remainder of the division of a polynomial $$f(x)$$ by $$(x - r)$$ is equal to $$f(r)$$ .

What is synthetic division?

Synthetic division is a simplified form of polynomial long division used when dividing by linear factors.

Define a root of a polynomial.

A root of a polynomial is a value of $$x$$ that makes the polynomial equal to zero.

What is the Factor Theorem?

The Factor Theorem states that a polynomial $$f(x)$$ has a factor $$(x - r)$$ if and only if $$f(r) = 0$$ .

What is the standard form of a polynomial?

The standard form of a polynomial is written in descending order of the degree of its terms.

What is the difference between a monomial and a polynomial?

A monomial is a single term, while a polynomial is a sum of one or more monomials.

What does it mean for two polynomials to be equivalent?
