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.
square the first term, plus twice the product of the first and the secon, then square the second.
Is the coefficient of the square a prime number? eg if the equation begins 3a2 then the factors must be (3a +/- x)(a +/- y)
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)
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
The first number is divisible by the second number
Factor out the Greatest Common Factor.
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
The first step in factoring a polynomial with four terms is to look for a common factor among the terms. If no common factor exists, you can try grouping the terms into two pairs and factor each pair separately. This often reveals a common binomial factor that can be factored out, simplifying the polynomial further.
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.

The expression (64 - x^2) can be factored using two distinct methods. First, it can be recognized as a difference of squares, which factors into ((8 - x)(8 + x)). Alternatively, it can be expressed by rewriting it as (- (x^2 - 64)), and then factoring as (- (x - 8)(x + 8)). Both methods yield the same factors but highlight different aspects of the expression.
The laws of factoring polynomials include several key principles: First, identify common factors among terms to factor them out. Second, apply special factoring techniques, such as the difference of squares, perfect square trinomials, and the sum or difference of cubes. Third, use the quadratic formula or factoring by grouping for polynomials of higher degrees. Lastly, always check for irreducibility, ensuring the polynomial is factored completely.
To write a simplified expression in factored form, first identify common factors or patterns such as differences of squares, perfect squares, or the distributive property. Next, factor out the greatest common factor (GCF) if applicable. Then, look for any further factorization opportunities, such as factoring trinomials or using methods like grouping. Finally, rewrite the expression as a product of its factors, ensuring that it is in its simplest form.
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.
To express (15y + 40) in factored form, first, identify the greatest common factor (GCF) of the terms, which is 5. Factoring out the GCF, we get (5(3y + 8)). Thus, the factored form of (15y + 40) is (5(3y + 8)).
To factor the expression (6ab + 3ac), first identify the common factors in both terms. Here, the common factor is (3a). Factoring this out gives you (3a(2b + c)). Thus, the expression (6ab + 3ac) can be rewritten as (3a(2b + c)).
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.
