Algebra is the branch of mathematics that deals with finding unknown quantities using variables and solving equations. In 10th grade, we extend our understanding of algebra to include complex systems of equations, polynomials, rational expressions, quadratic equations, and matrices. This chapter bui
Key Concepts
A system of three linear equations
A system of three linear equations in three variables (x, y, z) can be solved using the elimination method. Each equation represents a plane in 3D spa
The Greatest Common Divisor (GCD)
The Greatest Common Divisor (GCD) or Highest Common Factor (HCF) of polynomials is found using the Euclidean algorithm (long division method). The Lea
Rational expressions are ratios of two
Rational expressions are ratios of two polynomials (p(x)/q(x) where q(x) ≠ 0). An expression is in lowest form when GCD of numerator and denominator e
Two methods exist
Two methods exist: (1) Factorization method - factor the polynomial and take square roots of each factor, checking that all factors appear an even num
A quadratic equation has the form
A quadratic equation has the form ax² + bx + c = 0 (a ≠ 0). Solutions (roots) can be found using: (1) Factorization - factor as product of linear term
