The length is 3 more than twice the width, so The area is 560, so Plug in and solve for W: Use the Quadratic Formula: Since the width can't be negative, I get . Calvin and Bonzo can eat 1260 hamburgers in 12 hours. If Calvin and Bonzo eat together, they can eat 480 hot dogs in 6 hours. Plug these into the first equation and solve for t: The solutions are and . Calvin rides his power boat up and down a drainage ditch.

When you throw a ball (or shoot an arrow, fire a missile or throw a stone) it goes up into the air, slowing as it travels, then comes down again faster and faster ... and a Quadratic Equation tells you its position at all times! There are many ways to solve it, here we will factor it using the "Find two numbers that multiply to give a×c, and add to give b" method in Factoring Quadratics: a×c = A very profitable venture.

The first sentence says one is the square of the other, so I can write The sum is 132, so Plug into and solve for B: The possible solutions are and .
