Algebra 76 - Completing the Square - part 2

Professor Von Schmohawk explains how to geometrically prove that quadratic expressions can be perfect squares, both for positive and negative bx terms. The video demonstrates solving quadratic equations using the completing the square method, including examples with negative and irrational coefficients. The lecture concludes with a preview of the quadratic formula.
