Multiply x^2-8x+15/3x * 8x/x-3
sergejj [24]
You must follow the steps below:

 1. First, you should apply the dstributive property:

 =(x²-<span>8x+15/3x)(8x/x-3)
 =(8</span>x³-64x²+120x)/3x(x-3)

 2. As you can see, the common factor in the numerator is: "8x". So, you have:

 =8x(x²-8x+15)/3x(x-3)

 3. Then, when you simplify, you obtain:

 =8(x²-8x+15)/3(x-3)

 Therefore, the solution is: 8(x²-8x+15)/3(x-3)
