r u familiar with factorising?

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

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

ajprincessBest ResponseYou've already chosen the best response.1
a^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?

so the factor of the a^24ab+3b^2 is 3 1 also a^23abab+3b^2 =a(a3b)b(a3b) =(a3b)(ab)?

a^25ab+6a^2 = (a2)(a3) i dont know next

cantverify1Best ResponseYou've already chosen the best response.0
can u help me with any number there, so that i can answer the others by myself.
 11 months ago

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

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

cantverify1Best ResponseYou've already chosen the best response.0
may i ask if this is correct a^25ab+6a^2 = (a2)(a3) because i didnt split it yet
 11 months ago

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

cantverify1Best ResponseYou've already chosen the best response.0
so is it all right if a^23ab+2b^2=(a1b)(a2b) a^24ab+3b^2=(a1b)(a3b) ?

ajprincess, 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
 11 months ago

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

cantverify1Best ResponseYou've already chosen the best response.0
its written a^25ab+6a^2? but i think it b

aj princess may i ask last one question? where did you start cancelling?
 11 months ago

cantverify1Best ResponseYou've already chosen the best response.0
so you didnt cancel anything?

ajprincessBest ResponseYou've already chosen the best response.1
First I factorised the denominators. then i found lcm.
 11 months ago

ajprincessBest ResponseYou've already chosen the best response.1
after 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?

Really sorry. have to leave nw.:(
