Solving Equations by Factoring

Zero-Factor Property If two numbers have a product of 0 then at least one of the numbers must be zero

Zero-Factor Property If two numbers have a product of 0 then at least one of the numbers must be zero

Quadratic Equation An equation that can be written in the form where a, b, and c are real numbers is a quadratic equation. This form is called standard form

Some surveyors are surveying a lot that is in the shape of a parallelogram.

Some surveyors are surveying a lot that is in the shape of a parallelogram. They find that the longer sides of the parallelogram are each 8 m longer than the distance between them

Some surveyors are surveying a lot that is in the shape of a parallelogram. They find that the longer sides of the parallelogram are each 8 m longer than the distance between them.

A function defined by a quadratic polynomial is called a quadratic function. Quadratic functions are used to describe the height of a falling object or the height a propelled object reaches at a specific time

If a toy rocket is launched vertically upward from ground with an initial velocity of 128 feet per second, then its height in feet after t seconds is a function defined by

If a toy rocket is launched vertically upward from ground with an initial velocity of 128 feet per second, then its height in feet after t seconds is a function defined by

If a toy rocket is launched vertically upward from ground with an initial velocity of 128 feet per second, then its height in feet after t seconds is a function defined by After how many seconds will the rocket be 220 feet above the ground

If a toy rocket is launched vertically upward from ground with an initial velocity of 128 feet per second, then its height in feet after t seconds is a function defined by After how many seconds will the rocket be 220 feet above the ground
