If the coefficient of the highest power of a variable of interest is negative.
well first u dont spell common coomon
Nothing: it can have either sign.
All you do is write the prime factorization. I'll do an example: 50y First, you find the prime factorization of the coefficent using a factor tree, but it won't let me do that, so this is what the prime factorization should look like: 2x5x5 Then you add the variable: 2x5x5xy When you have a negative coefficent, just put a negative one in front of your answer. -50y = -1x2x5x5xy
The binomial usually has an x2 term and an x term, so we complete the square by adding a constant term. If the coefficient of x2 is not 1, we divide the binomial by that coefficient first (we can multiply the trinomial by it later). Then we divide the coefficient of x by 2 and square that. That is the constant that we need to add to get the perfect square trinomial. Then just multiply that trinomial by the original coefficient of x2.
If that's + 32x, the answer is x(5x - 8)(5x - 4)
The possibilities are infinite. One set: 1. 2xy 2. 2x2y 3. 2x4y
find a greatest common factor or GCFin factoring a trinomial with a leading coefficient other than 1 the first step is to look for a COMMON factor in each term
That is true.
The first common factor is 1. The next (and only other common factor, their highest common factor) is 2.
First.. find the gcf of the coefficients.Second.. remember the word 'common' .. for the variables only variables that appear in all the monomials are common factors, look at the exponents of that common variable, use the smallest exponent for that variable.Third.. Put them all together.. that is the gcf.EX: Find the gcf for 15x2y6 and 12x3yzThe gcf of the coefficients, 15 and 12, is 3.x is a common variable ... its smallest exponent is 2 .... x2y is a common variable ... its smallest exponent is an understood 1 ... ynote that z is NOT a common variableSo the GCF is 3x2y
The first common factor of any set of integers is 1.
Let's try one. 30x2y3z4 + 42x4y5z2 Do the numbers first. Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6 For the variables, select the lowest exponent. The GCF of the above expression is 6x2y3z2
Factor out the Greatest Common Factor.
first you must factor the equation... (x - 7)(x + 2) x = 7 and -2 Your factors are 7 and -2
There is only one common factor of 5, 3, 7: 1
