Study Notes
Series Completion
- The next number in the series 16, 29, 42, 55, 68 is 81, indicating a consistent increment pattern of 13.
Algebraic Formulas
- For the equation A = (B - 2)(C + 5), with A set to 6 and B as 0, the value of C is calculated as -8.
- In the formula 3D = E - 3, when D is greater than -1, E must be positive.
Polynomial Factoring
- The polynomial x² - 3x - 18 factors into (x + 3)(x - 6), demonstrating the factorization technique used for quadratic equations.
- The expression 2x² - 2 factors to (2x + 2)(x - 1), showcasing factoring where a common term can be identified.
Expression Evaluation
- Evaluating the expression x² - 15x + 56 for x = 11 results in 12, exemplifying substitution in polynomials.
- For the unknown variable X, given Y = 27, Z = Y/9, results in X = 81 through multiplication of variables.
Additional Polynomial Factoring
- The repetitive claim about the formula 3D = E - 3 reinforces the relationship between D and E concerning their values.
