The only common factor to all terms is yz. → xy³z² + y²z + xyz = yz(xy²z + y + x)
(x-y) + (xy - 1) = (x - 1)(y + 1)
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
Xy/y = x
0
It is then x/y when simplified
The GCF is xy
x(y - 1)(y + 1)

Divide by 'x'; x2+xy/x = x(x+y)

x=y+3t Original formula: y2 -xy = 9t2 -3xt (assumes you meant "9 times t2 " and not (9t)2 ) y2 = xy +9t2 -3xt y2 - 9t2 = xy - 3xt (y-3t)(y+3t) = x(y-3t) (y-3t) = x
x+y
It is x^2 + xy + y^2
The only common factor to all terms is yz. → xy³z² + y²z + xyz = yz(xy²z + y + x)
