Add up to give 9, multiply to give 20
4 and 5
Simplify
(2x+3)/(2x+3)
1
Simplify each expression
(5x)/1-:10/x
x^2/2
Factorise the following
4x^2 - 2x

Factorise the following
x^2 - 9
(x-3)(x+3)
Simplify by factorising first
(x^2-36)/(x+6)
x-6
5 and -5
Simplify
(3(x-3)(x+9))/(6(x+2)(x-3))
(x+9)/(2(x+2))
Simplify each expression
(6(x+5)(x-5))/((x-2)(x+2)) xx ((x-1)(x+2))/(3(x+5)(x-1))
(2(x-5))/(x-2)
Factorise, then solve for the following
x^2+6x+8=0
(x+2)(x+4)=0
therefore x = -2 or x = -4
(200-8x^2)/(10+2x)
2(10-2x)
