General Formulas and Concepts:
Algebra I
- Terms/Coefficients/Degrees
- Expand by FOIL (First Outside Inside Last)
Step-by-step explanation:
Step 1: Define
(x + 7)(x + 1)
Step 2: Expand
- Expand [FOIL]: x² + x + 7x + 7
- Combine like terms: x² + 8x + 7
Answer:
[tex](x + 7)(x + 1) = {x}^{2} + 7x + x + 7 \\ = {x}^{2} + 8x + 7 \\ Answer:\: \: \: \: \: \: \boxed{{x}^{2} +8 x + 7}[/tex]
