Anatomy of an Algebraic Expression
\[ \mathbf{7x^2 - 4x + 9} \]
Term 1: \(7x^2\)
- • 7 is the Coefficient
- • x is the Variable
- • 2 is the Exponent (Power)
Term 2: \(-4x\)
- • -4 is the Coefficient
- • x is the Variable
- • Pro Tip: The minus sign belongs to the coefficient!
Term 3: \(+9\)
- • +9 is the Constant
- • Stands completely alone with no variables attached.
SEC_02
The Rules of "Like Terms"
Compatible Blueprint (Like Terms)
Must share identical variables and identical exponents.
- \(3x\) & \(-8x\) Match (\(x^1\))
- \(5a^2\) & \(12a^2\) Match (\(a^2\))
- \(7\) & \(-15\) Match (Constants)
Faulty Blueprint (Unlike Terms)
Cannot be combined if letters or exponents mismatch.
- \(4x\) & \(4y\) Wrong Var.
- \(9m^2\) & \(2m\) Wrong Exp.
- \(6k\) & \(6\) Constant vs Var.

Step-by-Step Assembly Protocol
Example Manual
Mission: Simplify the following algebraic expression completely: \(5x + 3 - 2x + 8\)
Phase 01
Scan & Shape
Identify match categories. Draw boxes, circles, or underlines. Keep signs attached!
\(5x\) \(+ 3\) \(- 2x\) \(+ 8\)
Phase 02
Group Together
Physically rewrite the expression, clustering compatible structures side-by-side.
\((5x - 2x)\) \(+\) \((3 + 8)\)
Phase 03
Combine
Calculate final coefficients and write the final simplified blueprint expression.
\(3x + 11\)

Construction Quality Check
I kept each term's operational sign (+ or -) permanently attached to its leading coefficient. I strictly matched both variable letters AND exponent powers before combining coefficients. I wrote the final output in descending mathematical order (exponents first, constants last).
