i said derz 2 wayz gul :P i used first method :P
basicaly im nt gna fully help u ahah but il start u of, u alwys need to get the x term out into the first bracket and then the first term in ur 2nd bracket has to gve the first coffiencet when timesd together wid the x from first bracket
like this:
(x+-b)(ax^2-cx+d)
so in our case we wud have:
(x...)(2x^2... ...)
nw u mve onto the 2nd coffiencnt in the original given term which was -15x^2 hw we gna get dis what do we have to tyms x by?
(x...)(2x^2-3x...) should give you the power of 2nd coffiencent and then what 2 numbers timesd 2geda gve u 42? 6 and 7 right nw sub those in using plus and minus till u get the correct answer or if u can see easily ul no its just both minus
sorry its really hard to explain on here its easily dun face 2 face aha!
