Introduction

Factoring a trinomial is a crucial concept in algebra, and it requires a deep understanding of the underlying mathematical principles. In this article, we will focus on factoring the trinomial 25y^2 - 31y + 6 completely. We will provide the factorization and indicate whether the polynomial is prime or not.

Understanding the Trinomial

A trinomial is a polynomial with three terms. In this case, the trinomial is 25y^2 - 31y + 6. To factor this trinomial, we need to find two binomials whose product is equal to the given trinomial.

Factoring the Trinomial

To factor the trinomial 25y^2 - 31y + 6, we can use the following steps:

Find the greatest common factor (GCF): The GCF of the three terms is 1, so we cannot factor out any common factor.
Use the quadratic formula: The quadratic formula is x = (-b ± √(b^2 - 4ac)) / 2a. In this case, a = 25, b = -31, and c = 6. Plugging these values into the formula, we get: x = (31 ± √((-31)^2 - 4(25)(6))) / 2(25) x = (31 ± √(961 - 600)) / 50 x = (31 ± √361) / 50 x = (31 ± 19) / 50
Simplify the expression: Simplifying the expression, we get two possible values for x: x = (31 + 19) / 50 = 50 / 50 = 1 x = (31 - 19) / 50 = 12 / 50 = 6/25
Write the factored form: The factored form of the trinomial is (5y - 2)(5y - 3).

Is the Polynomial Prime?

A polynomial is prime if it cannot be factored into the product of two binomials. In this case, the trinomial 25y^2 - 31y + 6 can be factored into the product of two binomials, (5y - 2)(5y - 3). Therefore, the polynomial is not prime.

Conclusion

In this article, we have factored the trinomial 25y^2 - 31y + 6 completely. We have also indicated that the polynomial is not prime. Factoring a trinomial is an essential concept in algebra, and it requires a deep understanding of the underlying mathematical principles. By following the steps outlined in this article, you can factor any trinomial and determine whether it is prime or not.
