10x^2+21xy-10y^2/45x^2-23xy+2y^2/4x^2-20xy+25y^2/18x^2-47xy+5y^2 divide express the answer in lowest term

Question

tkhunny · Answer

You will have to do better than that.  I explain:

a + b / c + d means $$a + \frac{b}{c} + d$$ (a+b)/(c+d) means $$\frac{a+b}{c+d}$$  I'm thinking you should be much more generous with parentheses or we can't tell what expression you intended.

Thanks should i retype the problem im having trouble factoring

tkhunny · Answer

Yes, please.  Add parentheses where you intend to group.  Maybe: (10x^2+21xy-10y^2)/(45x^2-23xy+2y^2)/(4x^2-20xy+25y^2)/(18x^2-47xy+5y^2).  I'm not sure.  It's a pretty complicated expression.  You'll have to be particularly clear.

anonymous · Answer

thats correct

tkhunny · Answer

Piece at a time:

10x^2+21xy-10y^2 = (5x-2y)*(2x-5y)

Youdo the next one.
