How to identify when a trinomial is not factorable

The video tutorial explains how to factor a trinomial where the leading coefficient is greater than one. It introduces the AC method, which involves multiplying the coefficients a and c, and finding factors of this product that add up to the middle coefficient b. The tutorial demonstrates the process with an example, showing that the trinomial is not factorable as no suitable factors exist. The video concludes by stating that the trinomial is already in its simplest form.

What is one method mentioned for factoring trinomials when the coefficient 'a' is greater than one?

• The quadratic formula

• The BC method

• The AC method

In the AC method, what is the product of 'a' and 'C' in the example provided?

• 11

• 30

• 25

• 15

What is the value of 'B' in the example used to explain the AC method?

• 6

• 5

• -1

• 1

Which pair of factors of 30 was NOT mentioned in the video?

• -10 and -3

• -15 and -2

• -30 and -1

• -7 and -4

What conclusion is reached about the factorability of the trinomial in the example?

• It is a prime number
