Algebraic expressions can be written in verbal, symbolic, or calculated forms. Verbal expressions use words to represent variables and relations, while symbolic expressions use symbols. To calculate an expression, values are plugged in for variables and the expression is evaluated. Expressions can also be factored by finding a greatest common factor and grouping like terms.
2. Write a verbal expression. Write an expression in symbolic form. Calculate the answer of an expression. Factor an expression. Algebraic Expressions
3. Expression A symbol or combination of symbols. It represents a value or relation. Verbal Expression Example- Three x plus two y equals zero. What is an Expression?
4. Symbolic Expression Example- 3x+2y=8. Calculate an Expression Plug in numbers for variables. What is an Expression?
5. Represents numbers, symbols and letters. Example- 2x+3(y+1)=4 = Two x plus three times the quantity of y plus one equals four. Verbal Expression
14. Write in Symbolic Form Four x minus three y equals twenty-four. 4x-3y=24 Write in a Verbal Expression. 3x+2z=45 Three x plus two z equals forty-five. Review
15. Calculate the answer. 5x-6y=? when X=5 & Y=3 5(5)-6(3)= 25-18 = 7 What is the GCF of… 15x^2+3x? 25y^3-5y^2 =3x. =5y^2 Review
