lesson notes:08 completing the square
As all polynomials can be factorised down to a combination of linear and quadratic factors, the solving of quadratic equations becomes an important process.
lesson notes:07 quadratic equations
All polynomials can be rewritten as a combination of linear and quadratic factors, so solving quadratics, along with solving linear equations are fundamental to mathematics
lesson notes:07 quadratic equations
If two things multiply together to equal zero, then one of those things must be zero.
