Factorise : - X2y - X + 3xy + 3

Factorise : - x²y - x + 3xy + 3

Sum

- x²y - x + 3xy + 3

= 3 - x + 3xy - x²y

= 1(3 - x) + xy (3 - x)

= (3 - x) (1 + xy) = (xy + 1) (3 - x)

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise using the grouping method :
x (6x - 5y) - 4 (6x - 5y)²

Factorise : a² - ab - ca + bc

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

Factorise : (a² − b²) c + (b² − c²)a

factorise: x²y² - 3xy - 40

factorise: 3a²x - bx + 3a² - b

factorise: b(c - d)² + a(d - c) + 3(c - d)

Factorise the following by grouping the terms:
2a + b + 3c - d + (2a + b)³ + (2a + b)²(3c - d)

Factorise the following by grouping the terms:
p²x² + (px² + 1)x + p
