### factoring - How to factorize this cubic equation ...

Jan 29, 2017· $\begingroup$ A common first step for introductory problems is to guess and check certain integers close to zero to see if it will equal zero. Zero is the easiest to check because that would mean the constant term is zero, thats not the case here. $1$ doesn't work because that would be $1-6+4=-1\neq 0$. $2$ happens to work since this would be $2^3-6\cdot 2 + 4 = 8-12+4=0$. Since $2$ …

### Cubics - StudyWell

Sketching Cubics. Firstly, identify whether the cubic is positive or negative. Then, substitute x = 0 into the cubic expression to identify the y -intercept. Next, factorise if possible and set y = 0 to identify the roots. Note that, in y = x ( x + 1) 2 for example, x = − 1 is a repeated root and the curve must touch the x …

### Factorising - Mathematics GCSE Revision

Factorising. Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3) (x - 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since ...

### Example 15 - Factorise x3 - 23x2 + 142x - 120 - Class 9 ...

May 29, 2018· Transcript. Example 15 Factorise x3 23x2 + 142x 120. Let p(x) = x3 23x2 + 142x 120 Checking p(x) = 0 So, at x = 1, p(x) = 0 Hence, x 1 is a factor of p(x) Now, p(x) = (x 1) g(x) g(x) = ( ( ))/(( 1)) g(x) is obtained after dividing p(x) by x 1 So, g(x) = x2 22x + 120 So, p(x) = (x 1) g(x) = (x 1) (x2 22x + 120) We factorize g(x) x2 22x + 120 x2 22x + 120 We factorize using the splitting ...
