the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)

Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.

How are algebraic expressions and equations alike?

Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
