Quadratics
A quadratic has highest power 2. Factorised form can reveal roots using the zero-product property.
Key ideas
- expand binomials
- factorise monic quadratics
- solve factorised equations
- roots
- parabola features introduction
Worked example: x²+5x+6=(x+2)(x+3).
Common trap: Factors must multiply to the constant and add to the x coefficient.
Key words
quadratic — degree-2 expression/equation
root — x-value giving zero
factor — part of a product
parabola — quadratic graph
zero-product property — if ab=0 then a=0 or b=0
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
