Quadratic Difference
Detailed App Info:
Application Description
Quadratic Difference is a powerful learning aid to help students factor quadratic expressions by the difference of squares.
Interactive Coaching Calculators and Guides combine to speed the learning process.
The Coaching Calculator factors quadratic expressions such as :
x² - 49
4 - 9x²
8x² - 1
54x² - 16
that give rise to linear factors with rational and irrational coefficients.
The Guide also looks at expressions such as :
(x - 3)² - 36
(x - 3)² - (x + 5)²
9(x + 6)² - 4x²
and shows how to factor any factorable quadratic expression by completing the square.
It's ideal for students as the menu design reinforces each problem solving step.
Examples highlight and simplify algebra that students find hard.
A mental workout section covers the solving of problems such as 43 × 37 and 25² using the difference of squares.
