11.1 From Linear to Quadratic: Meeting the Quadratic Equation
Point 3 of 5
11.1.3 Spotting the Three Coefficients a, b, c
Core idea
Line the equation up into standard form, and the number in front of the squared term is a, the one in front of the single x is b, and the lonely constant left over is c.
Module goal. Picking up from the last stage's linear equations, learn to spot equations with a squared term and understand both their standard look and what a "solution" means.
