Question

simplify to lowest terms. a^2/a+2b-4b^2/a+2b

Answer 1

because the denominator was same, just subtract numerators and simplify

Answer 2

how do ido that

Answer 3

like u subtracting 2 fractions 3/4 - 2/4 = (3-2)/4 right ?
so, a^2/a+2b - 4b^2/a+2b
= (a^2-4b^2)/(a+2b), agree ?

Answer 4

ok

Answer 5

now, can u factorise a^2-4b^2 ?

Answer 6

how do i factor that

Answer 7

a^2-4b^2 = (a+2b)(a-2b)
now, apply it to ur fraction. what u get ?

Answer 8

what do you mean

Answer 9

Ido not knw how to get the final answer

Answer 10

hmmm.. well, look this

hope, this make sense for u
