Factories:
`p ^(2)- 10 p + 25`

Factorise: p ^(2)- 10 p + 25

Factories: 4y ^(2) + 20y + 25

Factorise: 6p^(2) + 11p -10

The factorisaton of 25 - p ^(2) - q ^(2) - 2 pq is

10p^(2) + 11p + 3 =?

Factorise (i) 8p^3+(12)/(5)p^2+(6)/(25)p+(1)/(125) (ii) 27p^3-(9)/(2)p^2+(1)/(4)p-(1)/(216)

Factoris the expression. 63 p ^(2) q ^(2) r ^(2) s -9pq ^(2) r ^(2) s ^(2) + 15 p ^(2) qr ^(2) s ^(2) - 60 p ^(2) q ^(2) rs ^(2)
