Factorise: 2a2 - 17ab + 26b2

factorise: 2a² - 17ab + 26b²

Sum

2a² - 17ab + 26b²

= 2a² - 13ab - 4ab + 26b²

= a(2a - 13b) - 2b(2a - 13b)

= (2a - 13b) (a - 2b)

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise : a² - ab - ca + bc

Factorise : xy - ay - ax + a² + bx - ab

factorise: 1 - 18x - 63x²

factorise: 1 - 3x - 3y - 4(x + y)²

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

Factorise the following by grouping the terms:
9x³ + 6x²y² - 4y³ - 6xy

Factorise the following by grouping the terms:
8x³ - 24x²y + 54xy² -162y³

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

Factorise the following by grouping the terms:

`"p"^2 + (1)/"p"^2 - 2 - 5"p" + (5)/"p"`
