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

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 : x² - (b - 2)x - 2b

Factorise : a³ - a² - ab + a + b - 1

Factorise : ab(c² + d²) - a²cd - b²cd

factorise: 5 + 7x - 6x²

factorise: 8 + 6(a + b) - 5(a + b)²

Factorise the following by grouping the terms:
8(2a + b)² - 8a -4b

Factorise the following by grouping the terms:
x(x - 4)- x + 4

Factorise the following by grouping the terms:
xy(a² + 1) + a(x² + y²)

Factorise the following by grouping the terms:
x² - (p + q)x + pq
