배울 내용 ; Learn the difference between factoring, and finding actual zeros (x-intercepts). ; Learn simple factoring when a=1. Also known as A/C method. ; Learn factoring when a>1 also known as bottom up factoring.
The process by which we find the constituent factors of a higher-degree polynomial is called factoring polynomials. ; For example, by multiplying x+2 and x -1 we get x 2 +x-2, where x + 2 and x -1 are the factors of the expression x2+x-2. ; Thus, finding these factors from a given expression is called Factoring of Polynomial.
Example 2A: Finding Zeros by Factoring f(x) = x 2 – 4x – 12 x 2 – 4x – 12 = 0 (x + 2)(x – 6) = 0 x + 2 = 0 or x – 6 = 0 x= –2 or x = 6 Set the function equal to 0. Factor...

To understand how to factor polynomials, it is first helpful to understand something about factoring numbers. Factoring numbers is process whereby we determine what numbers are multiplied together to form a given quantity. For example · 18 = (6)(3) · 18 = (-6)(-3) · 18 = (2)(3)(3) · The last example is considered to be completely factored, since it is broken down into it’s prime factors (2 and 3 are prime numbers). When factoring polynomials it is done in a similar fashion. We are tryi...
Start with: 2x(x+3) + (x+3), Which is: 2x(x+3) + 1(x+3), And so: (2x+1)(x+3)
