The answer depends mainly on what you are trying to do. But factoring out the GCF is usually a good idea since it reduces the size of the numbers tat you are dealing with.

What is the difference of finding a special products and factoring?
square the first term, plus twice the product of the first and the secon, then square the second.
What is the first thing you should look for when factoring?
Is the coefficient of the square a prime number? eg if the equation begins 3a2 then the factors must be (3a +/- x)(a +/- y)
What is the quadratic formula used for?
The quadratic formula is used all the time to solve quadratic equations, often when the factors are fractions or decimals but sometimes as the first choice of solving method. The quadratic formula is sometimes faster than completing the square or any other factoring methods. Quadratic formula find: -x-intercept -where the parabola cross the x-axis -roots -solutions
How do you identify a common monomial factor?
Are you talking about factoring a polynomial and doing factorization by pulling a monomial out? If you have an equation that looks like (3x^2 +6yx + 12X^3) You would first look for the coefficient that can go into all of them = 3 in this case then what is a variable you can pull out of all of the in this case =x so you pull out 3x and you get 3x(x+2y+4x^2)
Whats it called when second number is a factor of the first number?
The first number is divisible by the second number
What is the first thing you do when factoring an expression?
Factor out the Greatest Common Factor.
In factoring a trinomial with a leading coefficient other than 1 what is the first step?
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
How do you factor the polynoimal x3-2x2-3x?
To factor the polynomial x^3 - 2x^2 - 3x, we first need to find its roots. We can do this by using synthetic division or factoring by grouping. Once we find a root, we can then factor out the corresponding linear factor and apply the remaining steps of long division or factoring by grouping to obtain the remaining quadratic factor.

How do you factor out completely x squared y minus y cubed?
To factor out the expression: x2y-y3 First factor out one "y": y(x2-y2) The expression x2-y2 is a difference of squares, which factors as well: (y)(x-y)(x+y) This is the simplest factoring of the original expression.
Why is it important to always factor the radicand first when simplifying radicals?
The question is based on the premise that It is not possible to simplify a radical without first factorising it. That is simply not true. Beginners may find it a useful step but that does not make it "important to always factor".Simplifying radicals entails removing square factors of the radicand from under the radical. This can be done without factoring first.
What is the first step in factoring?
Recognize whether the number is odd or even.
Can all quadratic equations be solved?
Well, that depends on what you mean "solve by factoring." For any quadratic equation, it is possible to factor the quadratic, and then the roots can be recovered from the factors. So in the very weak sense that every quadratic can be solved by a method that involves getting the factors and recovering the roots from them, all quadratic equations can be solved by factoring. However, in most cases, the only way of factoring the quadratic in the first place is to first find out what its roots are, and then use the roots to factor the quadratic (any quadratic polynomial can be factored as k(x - r)(x - s), where k is the leading coefficient of the polynomial and r and s are its two roots), in which case trying to recover the roots from the factors is redundant (since you had to know what the roots were to get the factors in the first place). So to really count as solving by factoring, it makes sense to require that the solution method obtains the factors by means that _don't_ require already knowing the roots of the polynomial. And in this sense, most quadratic equations are not solvable through factoring.
What is the definition of quadratic equation of factoring?
its easy first,xczxczxczxczxc....ERROR..vxbdxv
When was JLS's first gig?
They performed before The X Factor when they were called "UFO"
How can the factoring of the first equation help you factor the second equation 9x2 power 18x plus 8 9a2power 18ab plus 8b2power?
The first equation factors to (3x + 2)(3x + 4) The second equation factors to (3a + 2b)(3a + 4b)
What are the first three common multiples for 5 and 12?
factoring 5 factored =1*5 12 factored =2*2*3 no common factor so the LCM is 60 the next multiples would be 120 and 180
