Solving Simultaneous Linear and Quadratic Equations (VCE SSCE Mathematical Methods): Quizzes

Where a straight line and parabola intersect

0, 1, or 2

A line that touches the curve at one point

Write both equations with $y$ as subject

Set the two expressions equal and solve

$(2, 0)$ and $(4, -4)$

Substitute into either original equation

The line is a tangent (one solution)

$(1, 0)$ only

$x^2 - 6x + 8 = 0$
