Factorise : 3x5 - 6x4 - 2x3 + 4x2 + X - 2 - Mathematics

Factorise : 3x⁵ - 6x⁴ - 2x³ + 4x² + x - 2

Sum

3x⁵ - 6x⁴ - 2x³ + 4x² + x - 2

= 3x⁴ (x - 2) - 2x² (x - 2) + 1 (x - 2)

= (x - 2) (3x⁴ - 2x² + 1)

Factorise by the grouping method:

ab (x² + 1) + x (a² + b²)

Factorise by the grouping method : a² + b - ab - a

Factorise : 3a²b - 12a² - 9b + 36

factorise: x² + 4x + 3

factorise: 8 + 6(a + b) - 5(a + b)²

factorise: 15(5x - 4)² - 10(5x - 4)

Factorise the following by grouping the terms:
15xy - 9x - 25y + 15

Factorise the following by grouping the terms:
9 + 3xy + x²y + 3x

Factorise the following by grouping the terms:
4abx² + 49aby² + 14xy(a² + b²)

Factorise the following by grouping the terms:

`(1)/(25x^2) + 16x^2 + (8)/(5) - 12x - (3)/(5x)`
