hi again, guys ..
does anyone here , knows how to do this question below in red:
(x-y)2=1 and 4xy=15, find the value of (2x-3y)2-5y2
incase you guys doesn't know what i'm talking about,
let me re-write the question once again in longer term .
(x-y)(x+y)= 1 and 4xy= 15 , find the value of (2x+3y)(2x-3y)- 5(y)(y) .
the answer is -11 .
but , i doesn't know the steps for it .
if any math experts know the steps for the question above ,
kindly post on the tagboard ,
thanks gratefully .
