How to factorise trinomials using the (P)roduct (S)um (F)actors method.

2008年3月12日 · Factorise using the PSF Method. 4y² + 4y - 3. P = Product of first and last terms = -12y² (typo) S = Sum (what does "Sum" refer to?) or middle term = 4y. F = Factors of P that give S = 6y, -2y. ∴ 4y² + 4y - 3 = 4y² + 6y - 2y - 3. = 2y (2y + 3) - 1 (2y + 3) [How did it go from this: "2y (2y + 3) - 1 (2y + 3)" to this " (2y + 3) (2y - 1)"?????]

The factorisation technique referred to as the "Cross Method" is described in detail. It is the most preferred method by students to use to complete the factorisation of quadratic expressions and quadratic equations. Some teachers still prefer the generally more difficult PSF method.

PSF method. The PSF (Product, Sum, Factor) method uses a similar idea we had with monic quadratics where we think about sums and products, but slightly different.

PSF method (or 'splitting the middle term') The PSF (Product, Sum, Factor) method uses a similar idea we had with monic quadratics where we think about sums and products, but with a slight difference. This method is also called 'splitting the middle term'.

Examples: Decimals on the Number Line Example 5 a) Plot 0.2 on the number line with a black dot. b) Plot 0.43 with a green dot. Solution: For 0.2 we split the segment from 0 to 1 on the number line into ten equal pieces between 0 and 1 and then count
