- This section covers Quadratic Equations. In algebra, any expression of the form ax 2 + bx + c where a ≠ 0 is called a quadratic expression. It is useful to remember these results of expanding brackets: (x + a) 2 = x 2 + 2ax + a 2 (x - a) 2 = x 2 – 2ax + a 2 (x + a)(x – a) = x 2 – a 2
- Sequences are sets of numbers that are connected in some way. In a quadratic sequence, the difference between each term increases, or decreases, at a constant rate.
- Solving Quadratic Practice Questions. 1. Find 2 numbers that sum to 21 and the sum of the squares is 261. a. 14 and 7 b. 15 and 6 c. 16 and 5 d. 17 and 4. The quadratic formula to find the roots of a quadratic equation is: x1,2 = (-b ± √∆) / 2a where ∆ = b2 - 4ac and is called the discriminant of the...
