Algebra Concepts and Problem Solving

Miss Tai reviews five types of questions that will appear on the new Algebra 1 Regents exam. The video covers combining like terms with radicals, finding the equation of a line using point-slope form, rationalizing denominators, completing the square for quadratic equations, and solving quadrilinear systems. Each section provides detailed explanations and examples to help students prepare for the exam.
