Factorisation by Grouping

On factorising 14pq + 35pqr, we get:

• pq(14+35r)

• p(14q+35qr)

• q(14p+35pr)

• 7pq(2+5r)

Choose the correct answer:
The factorisation of 25x²y - 5xy is  

• 5xy (5x - 1)
• 5xy (5x + 1)
• 5xy (5x + 5)
• 5xy (x - y)

• (x+2)(3y+4)

• (3y+2)(x+4)

• (x+3y)(x+4)

• (x+2)(x+3y)

• (5c+6)(1-k)

• (k-1)(5c-6)

• (k+1)(5c-6)

• (5c+6)(k-1)

• (a+2b)(a+c)

• (a+c)(a+b)

• (a+b)(b+c)

• (a+b)(a+2c)
