Factoring Trinomials: a > 1

Question 7 • FL-1200700-Mathematics for College Algebra MIS

What is the factored form of 36x4 – 25?

Answer

(6x2 – 5)(6x2 + 5)

(6x2 – 5)(6x2 – 5)

(6x2 – 25)(6x2 + 25)

(6x2 – 25)(6x2 – 25)

Recognize 36x⁴ − 25 as a difference of squares: (6x²)² − 5². Apply a² − b² = (a − b)(a + b), giving (6x² − 5)(6x² + 5). This matches choice A.
