Adding and subtracting fractions with unlike denominators?
You have to make your unlike denominators to like. Do that by finding the common factor for each set of fractions. Remember, that what you do with the numerator you do with the denominator ( lets say you want to add 1/2 + 2/4)( divide or multi by the same factor) 1/2 = 1 x2= 2 this makes 2/4 and now you can add 2/4 + 1/4= 3/4 2 x2=4 Hope this helps. It hard to explain online like this.
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 do you do when you are dividing exponents and there are 3 number as a numerator and only 1 as the denominator?
Subtract them. example: x3 --- x1 Subtract the 1 from the 3 and you get x2 over 1 or just x2
What is the highest common factor of 100 and 96?
2 to the third power x2=highest common factor of 100 and 96=16
What is X2 plus X2?
x2 + x2 = 2x2
What is the least common denominator for x2 plus 3x?
3x2
What is the GCF of 3x squared plus 2x - 5?
3x2 has x, x2 , and 3 as factors. 2x-5 does not have any of those as factors. So the greatest common factor is 1. If you were adding rational expressions with those two expressions in the denominator, you would need to multiply them together to find the least common denominator.
Does a rational function have all three types of asymptotes in its graph?
Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1.
What is the least common multiple of x and x plus 2?
x2 + 2x
What is the least common multiple of x2-1 and x-1?
Since x2 - 1 is a multiple of x - 1, it is the LCM of this problem.
What is the least common multiple of x2-x and x-4?
6
What is the least common multiple of x plus 4 and x-1?
Their product.
What is a common factor of x2-16 and x2-4x?
x2 - 4
How do i divide x2 - x - 12 by x - 4?
x2 - x - 12First try and factor that expression.Notice that it happens to be the product of (x - 4) and (x + 3). This makes your problem easy.(x2 - x - 12) / (x - 4)= (x - 4) (x + 3) / (x - 4)Now just divide numerator and denominator by the common factor. ("Cancel" (x - 4) out of numerator and denominator.)Wind up with the answer = (x + 3)

What is one over x plus eight plus six over x minus eight?
Grammar in mathematics is important so that the question cannot be misunderstood. The question is asking for the solution to 1/(x + 8) + 6/(x - 8). Where fractions are being added or subtracted then the denominators need converting to a common denominator. With numbers this new denominator would be the Lowest Common Multiple. With algebraic terms then simply take the product. The common multiple of (x + 8) and (x - 8) is (x + 8)(x - 8) = x2 - 82 1/(x + 8) = 1 x (x - 8)/x2 - 82 = x - 8/x2 - 82 6/(x - 8) = 6 x (x + 8)/x2 - 82 = 6x + 48/x2 - 82 1/(x + 8) + 6/(x - 8) = x - 8/x2 - 82 + 6x + 48/x2 - 82 = 7x + 40/x2 - 82
What is this quadratic equation written in standard form x2 - 10x - 6 equals 2x plus 1?
x2 - 10x - 6 = 2x + 1 Subtracting 2x + 1 from both sides gives: x2 - 12x - 7 = 0
