What is the least common multiple for x2-x and 8x-4?
The two numbers are x2 - x and 8x - 4. The least common multiple is the product of the numbers divided by their greatest common factor. For this example, I will assume that x is a positive integer > 1, since otherwise x2-x = 0, and the least common multiple would then be 0. So, the next step is to determine the greatest common factor. To do that, factor each of the numbers. These numbers can be rewritten as x(x-1) and 4(2x-1). The factors of x2 - x are x and x-1. The factors of 8x - 4 are 2, 2, and 2x-1. Neither x nor x-1 evenly divide 2x-1. However, either x or x-1 is even, which means one of them is divisible by 2. Since 2 is a factor of 8x-4, the greatest common factor is at least 2, but since we do not know the value of x, the greatest common factor might be 4. So, the least common multiple is either (x2-x)(8x-4)/2 = (8x3-12x2-4x)/2 = 4x3-6x2-2x or (x2-x)(8x-4)/4 = (8x3-12x2-4x)/4 = 2x3-3x2-x.

What is the LCM for 8x 18xy?
To find the least common multiple (LCM) of 8x and 18xy, we need to identify the highest power of each prime factor that appears in either number. The prime factors of 8x are 2 and x, while the prime factors of 18xy are 2, 3, x, and y. The LCM is the product of the highest power of each prime factor: 2^3 * 3^1 * x^1 * y^1 = 24xy. Therefore, the LCM for 8x and 18xy is 24xy.
What is the gcf of 8x plus 16?
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one expression, 8x+16, in the question!
WHAT IS -8x-10 plus -20 equals?
-8x - 10 - 20 = -8x - 30
