Question

180/(х-15) -180/х -3/5​

Answer 1

Ответ:

13500-3x²+45x/5x²-75x

Объяснение:

180/x-15-180/x-0,6

180/x-15-180/x-3/5

900x-900(x-15)-3x*(x-15)/5x*(x-15)

900x-900+13500-3x²+45x/5x²-75x

Answer 2

To simplify the expression, let's find a common denominator for the fractions. The common denominator is 5х(х - 15). We can rewrite the expression as follows:

(180 * 5х - 180 * (х - 15) - 3х(х - 15))/(5х(х - 15))

Simplifying further:

(900х - 180х + 2700 - 3х² + 45х)/(5х(х - 15))

Combining like terms:

(720х + 2700 - 3х²)/(5х(х - 15))

So, the simplified expression is (720х + 2700 - 3х²)/(5х(х - 15)).
