Best ResponseYou've already chosen the best response.0you start w/ different denominators to get a common denominator with binomials multiply them together (x+4)(x2) For first fraction you added (x2) so multiply the top by (x2) 4*(x2) For 2nd fraction you added (x+4) so multiply top by (x+4) 7*(x+4) this gives 4(x2)  7(x+4) all over (x+4)(x2) distribute on top and add like terms 4x87x28 =3x36 factor out a 3 =3(x+12) this is still all over (x+4)(x2) hope that helps

Best ResponseYou've already chosen the best response.0u wil get it by l.c.m , 4(x2)7(x+4) whole divided by (x2)(x+4) (4x87x28) whole divided by(x2)(x+4) (3x36) whole divided by (x2)(x+4) u take 3 common from numerator u wil get u r answer
