Learn the ac method for factoring and solving a quadratic equation

we find two factors of the product of the constant term (the term with no variable) and the coefficient of the squared variable whose sum gives the linear term. These factors are now placed in separate brackets with x to form the factors of the quadratic equation.
There are other methods that can be used to achive this including the AC, Berry, Box, Grouping, diamond and mental technique. Once we have factored the quadratic equation, we then apply the product property to solve our equation. When solving a quadratic equation we call our solutions the zeros, x-intercept, and roots.

@neambler Год назад

I love the large X idea to separate everything. It helps me sort what steps I need to take. This whole videos is great. I, too, was confused about why it was 3x+1, but zee Unveil explained below about how you "merge" the two 3x-5's because they're the same factor. So, you're left with one of the (3x-5)'s and the two remainders, which are (3x+1). That's an important step to explain next time. Still...tyvm, good sir! :)

@jeffw1267 2 года назад

The quadratic method is super easy in this case and it took me about 60 seconds to find the roots AND plug them into the equation. If A (the coefficient of the x^2 term) is not 1 or 2 then I don't waste time trying to factor it manually. The quadratic formula never fails.

Oh, for those who don’t know, I figured it out. You put into parentheses one of the original expressions you had. In this case: (3x-5) Then put into parentheses the two outside terms. This being 3x and 1 to get (3x+1) So then you write it as (3x+1)(3x-5)
