The unknowns in the polynomials actually represent numbers. What do we do when we know these numbers and plug them into the polynomials? Let's practice here in this section.

Basic Concepts: Evaluating algebraic expressions

- 1.Evaluating polynomialsa)When ${ 4x^2-3 }$ is evaluated for ${x=5,}$ what is the result?b)Find the value of "${-x^4-3x^3}$" when ${x=-3}$
- 2.Find the value of the following polynomials, given $a = 2$ and $b = 5$.a)$\frac{1}{2}a^3-3b$b)$3ab+5b^2-10a$c)$a^2b^2-3ab$
