a)3/5x + 1/x+2
can be written as a single fraction in the form ax+b/5x(x+2) where a and b are integers.
Work out the value of a and the value of b.
a =
b=
b) Factorise 4(x + y) + (x + y)^2
to give them the same denominator, multiply 3 by (x+2) and 1 by (5x) 3(x+2) = 3x+2 and 1(5x)= 5x now we have 3x+6/(5x)(x+2) and 5x/(5x)(x+2) adding the numerators gives us
