Best ResponseYou've already chosen the best response.1first you need to factor x^2 + 12x + 35 the factors will look like (x + a)(x + b) where a*b = 35 and a + b = 12 so can you work out the values of a and b are?

Best ResponseYou've already chosen the best response.1right good now we need to factor the denominator

Best ResponseYou've already chosen the best response.1right so we have (x + 5)( x + 7)  3 ( x + 5)

Best ResponseYou've already chosen the best response.1No that is wrong rhrh12 you cannot divide those terms because the top and bottom are sums not products

Best ResponseYou've already chosen the best response.1that's easy factor 2x  12 then simplify

welshfella

Best ResponseYou've already chosen the best response.1easy also factor 4x + 16

welshfella

Best ResponseYou've already chosen the best response.1right now simplify 4(x + 4)  6

Best ResponseYou've already chosen the best response.1what is a common factor of 4 and 6?

welshfella

Best ResponseYou've already chosen the best response.1right so divide 4 and 6 by 2

Best ResponseYou've already chosen the best response.1you divide top and bottom by 2 to get 2 / 3

Best ResponseYou've already chosen the best response.1then hopefully you can do the rest yourself thats the best way to learn  practice them yourself

Best ResponseYou've already chosen the best response.1factoring 4x^2  7x + 3 is a bit more difficult than those with x^2 only

welshfella

Best ResponseYou've already chosen the best response.1you know that the letters a and b must be 3 and 1 because they product is + 3 and you need 7x in the middle

Best ResponseYou've already chosen the best response.1so its 4x and x as first part of the 2 bracketes dw:1438446430986:dw

welshfella

Best ResponseYou've already chosen the best response.1so top part is (4x  3)x  1)

welshfella

Best ResponseYou've already chosen the best response.1the bottom part is easier you need 2 numbers whose product is 6 and whose sum is + 5

welshfella

Best ResponseYou've already chosen the best response.1so it must be 6 and + 1 or +6 and 1

welshfella

Best ResponseYou've already chosen the best response.1you are right so we have (4x  3)(x  1)  (x + 6)(x  1)
