Best ResponseYou've already chosen the best response.1good:) can u factorise a^23ab+2b^2?

Best ResponseYou've already chosen the best response.1Nope:( Can u tell me two factors of 2 such that their sum is 3?

ajprincess

Best ResponseYou've already chosen the best response.1a^23ab+2b^2 the factors of 2 whose sum is 3 are 1 nd 2. split the middle term 3ab using this. then u will get a^22abab+2b^2 =a(a2b)b(a2b) =(a2b)(ab) Is it clear?

Best ResponseYou've already chosen the best response.0so the factor of the a^24ab+3b^2 is 3 1 also a^23abab+3b^2 =a(a3b)b(a3b) =(a3b)(ab)?

Best ResponseYou've already chosen the best response.0can u help me with any number there, so that i can answer the others by myself.

Best ResponseYou've already chosen the best response.1good:) so a^23ab+2b^2=(a2b)(ab) a^24ab+3b^2=(a3b)(ab) a^25ab+6a^2 = (a2)(a3)

Best ResponseYou've already chosen the best response.1can u find thw l.c.m of (a2b)(ab), (a3b)(ab) and (a2)(a3)?

Best ResponseYou've already chosen the best response.0may i ask if this is correct a^25ab+6a^2 = (a2)(a3) because i didnt split it yet

ajprincess

Best ResponseYou've already chosen the best response.1nope:( sorry i didnt notice it. if it is a^25ab+6b^2, then a^25ab+6b^2= (a2b)(a3b)

Best ResponseYou've already chosen the best response.0so is it all right if a^23ab+2b^2=(a1b)(a2b) a^24ab+3b^2=(a1b)(a3b) ?

Best ResponseYou've already chosen the best response.0ajprincess, can you solve any number there then ill do the rest so that i can follow. because its 2am here and i need to sleep thanks for your help btw

Best ResponseYou've already chosen the best response.1is it a^25ab+6a^2? or a^25ab+6b^2?

Best ResponseYou've already chosen the best response.0aj princess may i ask last one question? where did you start cancelling?

anonymous

Best ResponseYou've already chosen the best response.0so you didnt cancel anything?

Best ResponseYou've already chosen the best response.1First I factorised the denominators. then i found lcm.

ajprincess

Best ResponseYou've already chosen the best response.1after finding the lcm i multiplied each fraction both up and down to make them have the common denominator. the common denominator is (m+3)^2(m+2) but the denominator of the first fraction is (m+3)(m+2). To make it (m+3)^2(m+2) i multiplied by (m+3). if i multiplied the denominator then i should multiply the numerator by the same in order to keep the fraction the same. getiing it?
