Answer:
1. Expression
2. Equation
3. Equation
4. Expression
5. Equation
6. Expression
Step-by-step explanation:
Algebraic Equation is basically algebraic expression except there's one difference.
Algebraic Equation must always have = sign.
The = sign applies to all equations, no matter what equation it is.
Next is Algebraic Expression;
Algebraic Expression does not have =, <, ≠, >, ≤ and ≥.
To put it simply, algebraic expression is just terms there; no comparison between two.
Usually, algebraic expression refers to polynomial, square root, etc.
So now, you understand the difference between two?
- Algebraic Equation has =
- Algebraic Expression does not have any comparisons (>, = as examples)
1. 2x^2-3x+1 is algebraic expression because there is no comparison.
2. x^3-2x^2=x is algebraic equation because there is comparison between two expressions.
3. x^2-5x+6=0 is algebraic equation because there is comparison between one expression and a constant.
4. 5x+20 is algebraic expression because there is no comparison.
5. y = -2x+3 is algebraic equation because there is comparison between x-term and y-term.
6. -x-5 is algebraic expression because no comparison.
