This math topic focuses on solving advanced polynomial and quadratic expressions involving squared variables and coefficients under a square root. Problems require simplifying polynomial expressions, extracting square roots, and determining the values of variables (such as 'd', 'x', 'n', 'r', 'b') that satisfy the equations. The expressions are structured to challenge understanding of polynomial behavior, quadratic formulas, and algebraic manipulation without the use of a calculator. The skill level indicated is advanced, suitable for deeper comprehension and application of polynomials and quadratics concepts.
