**1. About Factorising Trinomials **

- A trinomial means having 3 terms
- An example of a trinomial is x² + 3x – 10
- Factorising a trinomial means to put into brackets

.

**Example 1**: Factorise *x² + 3x – 10*

*Take the number term –10**Take the x coefficient term 3**Find two numbers which multiply to give –10 and add to give 3**The numbers 5 & – 2 are placed into two brackets to give (x + 5)(x – 2)**Answer is: x² + 3x – 10 = (x + 5)(x – 2)*

.

**Example 2**: Factorise 2*x² + 7x – 15*

- Multiply the 2 x -15 (first & last terms) and place the -30 on the RHS of the page
- Find two numbers which multiply to give -30 & add to give +7 (x coefficient): use -3 & 10
- Replace 7x for -3x + 10x to give: 2
*x² + 7x – 15*⇒ 2*x² – 3x + 10x – 15* - Factorise the 1st & 2nd two terms: ⇒ x(2
*x – 3) + 5(2x – 3)* - (x & 5) is first bracket & (2x – 3) the second: ⇒ (x
*+ 5)(2x – 3)*

.

Once a trinomial has been factorised, you may be asked to;

- Solve ⇒ Find the Roots ⇒ put y = o and solve for x
- Sketch ⇒ See Below

.

Sketching a Trinomial

- Identify if either a max or min shape
- Find the y-intercept ⇒ make x = 0 and solve for y
- Find the roots ⇒ make y = 0 and solve for x
- Find the axis of symmetry ⇒ Can use the Midpoint Formula
- Find the coordinates of the turning point ⇒ substitute the midpoint x to get y
- The sketch below shows a parabola with equation y = – x² + 2x + 3
