How do you factor 2y^2 +5y-18?
1 Answer
Explanation:
We can use the "AC Method" (at least that was the name of the method, which I will explain further, that I was taught) to factor the quadratic equation
Why is it called the "AC Method," you may ask?
In the standard quadratic equation
The
So in this method, what we do first is multiply the
Then we find factors that will result in the product of
Aha! We have found
Now we expand and write an unsimplified version of the equation.
Now we factor by grouping...
Notice I just paired two terms in the expanded form of the equation and factored through GCF (Greatest Common Factor). Also, notice the sharing of the expression
Put
That's it! Our factored equation is
*I suggest you look for videos for this method because explaining it through written words, speaking from my experience, did not help me fully grasp the concept. *
