How do you Factorise an expression completely?

To factorise an expression fully, take out the highest common factor (HCF) of all the terms. For example, is the HCF of 4 x 2 and as 2 is the biggest number that will divide into 4 and 6 and is the biggest variable that will divide into and .

Can x 2 2x 2 be factored?

Explanation: This is not factorable normally. We can see this since x2−2x+1 is a perfect square, so it touches the x-axis at a single root. Adding 1 to this produces x2−2x+2 , and raises the graph of y=x2−2x+1 one upwards, meaning it no longer touches the x-axis, so it has no real roots.

What are the factor of x2 2x 1?

So the polynomial factors into, x^2 – 2x – 1 = {x – r+} * {x – r-}. x^2 – 2x – 1 = {x – [1 + sqrt(2)]} * {x – [1 – sqrt(2)]}. Carry out the multiplication and you will find that the two sides of this equation are equal.

How do you Factorise 2 terms?

How to Factor Trinomials with Two Variables?

1. Multiply the leading coefficient by the last number.
2. Find the sum of two numbers that add to the middle number.
3. Split the middle term and group in twos by removing the GCF from each group.
4. Now, write in factored form.

What is the factored form of 9×2 25y2?

Therefore 9×2 – 25y2 in factored form Is (3x – 5y)(3x + 5y).

How do you factor a polynomial with two groups?

Group the first two terms and the last two terms. Factor out the greatest common factor ( GCF) from each group. Factor the polynomial by factoring out the greatest common factor, 2x−1 2 x – 1.

What is factoring and how do you use it?

Factoring is a useful way to find rational roots (which correspond to linear factors) and simple roots involving square roots of integers (which correspond to quadratic factors). Polynomials with rational coefficients always have as many roots, in the complex plane, as their degree; however, these roots are often not rational numbers.

What is the best tool for factoring polynomials?

Wolfram|Alpha is a great tool for factoring, expanding or simplifying polynomials. It also multiplies, divides and finds the greatest common divisors of pairs of polynomials; determines values of polynomial roots; plots polynomials; finds partial fraction decompositions; and more.
