(x-5)(x+11)
15t+25 = 5(3t+5)
25x + 75 = 25*(x + 3)

To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5
(x-5)(x+11)
15t+25 = 5(3t+5)
-9(a + b)
25x + 75 = 25*(x + 3)
x(2+3)-70 5x-70 70/5= x-14
2(3n+4)
we factorise a number by finding the common factor. example: 2x+6 = 2 is the common factor the 2 is then put outside the bracket 2x+6 = 2(x+3)
