Solve Quadratic Systems (HSC SSCE Mathematics Advanced): Flashcards

Finding where two functions intersect

Points where two graphs cross or meet

Set the two functions equal: $f(x) = g(x)$

$\Delta = b^2 - 4ac$

Two intersection points

One intersection point (tangent)

No intersection points

Plot both, identify where they intersect

Quadratic formula (most reliable)

Quicker than quadratic equation
