What is the AC method of factoring?
The AC Method is a method of factoring trinomials in the form ax2 + bx + c. It forms an alternative to the “guessing method.” Given a quadratic expression with the terms ax2 + bx + c, we are often asked to factor. What we are being asked to do is find two expressions, which multiply to give the original expression.
Why does the AC method work for factoring?
When factoring trinomials with a leading coefficient of one, we found a pattern that allowed us to factor the trinomial quickly. So by multiplying ac in a trinomial, then using the factors of ac whose sum is b, that allows us to rewrite the linear term of the polynomial as a sum of two linear terms.
What is AC test method?
AC test is a method of testing whether a quadratic trinomial is factorable or not. It is also a method of identifying the factors of a general quadratic trinomial Ax2 + B(x) + C. A quadratic trinomial is factorable if the product of A and C have M and N as two factors such that when added would result to B.

What is trinomial method?
The “AC” method or factoring by grouping is a technique used to factor trinomials. A trinomial is a mathematical expression that consists of three terms (ax² + bx + c).
What is the formula for factoring Trinomials?
To factorize a trinomial of the form ax2 + bx + c, we can use any of the below-mentioned formulas: a2 + 2ab + b2 = (a + b)2 = (a + b) (a + b) a2 – 2ab + b2 = (a – b)2 = (a – b) (a – b) a2 – b2 = (a + b) (a – b)
What is the factoring method?
Factoring is the process by which we go about determining what we multiplied to get the given quantity. A common method of factoring numbers is to completely factor the number into positive prime factors. A prime number is a number whose only positive factors are 1 and itself.
How to factor a variable using the ac method?
Here are some steps to follow when factoring using the AC Method. Multiply a by c and write it in the first column (factors) of the t-chart shown below. Write b in the second column (sum). Find factors of ac that have a sum of b. Make a box and fill in the terms shown below. Don’t forget to put your variable with your factors!

Can a quadratic expression be factored using the ac method?
When you have a quadratic expression, you can factor it using the AC Method. Here are some steps to follow when factoring using the AC Method. Check for a GCF – if there is one, factor like you did in the GCF lesson, if there is not, move to step 2
