Evaluate the expression of (a–b)². If a= 3 and b= –5, at a= 3 and b= –5.

If a= 3 and b= –5, evaluate a² – b².

If a= 5 and b= –7, evaluate 2|a| –3|b|.

Evaluate the expression x² – 2xy + y² at x= –3 and y= 2.

Add: (3x – 2) + (3x² + 6x)

Subtract: (2a² + 5a +3) – (a² – 3a – 4)

Find the missing term: (2x + _____) + (3x² – 4x + 3) = 3x² – 2x – 8

Add: (x – 2) + (x + 2) + (x –1) + (x + 1)

Simplify: 9x² – (5x² – 8) – (–3x – 1)

Adding or subtracting polynomials involves combining like terms.

When adding or subtracting polynomials, the degree of the resulting polynomial can be different from the original polynomials.

The result of evaluating an algebraic expression can never be negative.

The order of operations (PEMDAS/BODMAS) must be followed when evaluating algebraic expressions.

In subtracting polynomials, changing the order of the terms does not affect the result.

When subtracting polynomials, it's important to distribute the subtraction sign(–) to all terms in the second polynomials

Algebraic Expressions can involve operations like addition, subtraction, multiplication, and division.

In algebraic expressions, variables always represent specific numerical values.

The process of adding or subtracting polynomials involves only terms with variables raised to the same power.

Parenthesis in algebraic expressions indicate multiplication only.
