Best ResponseYou've already chosen the best response.0Common denominator is 3(c + 4) so you put that on top of each term. 3(c+4)*4 3(c+4)*1 2c  + =  3(c+4) c + 4

Best ResponseYou've already chosen the best response.0(a  3)a = (a + 3)2a  (a + 3)(a  3) a^2  3a = 2a^2 + 6a  (a^2  9) a^2  3a = 2a^2 + 6a  a^2 + 9 distribute the  sign a^2  3a = a^2 + 6a + 9 add like terms 3a = 6a + 9 subtract a^2 from both sides 9a = 9 subtract 6a from both sides a = 1
