Which polynomial has a factor of (3X - 5) along with (4X + 1)?

Which polynomial has a factor of (3X - 5) along with (4X + 1)?

• A. 12X² - 17X - 5
• B. X² - 5
• C. 4X² + 5
• D. 3X² + 5X

Answer: (A)

To determine which polynomial has both (3X - 5) and (4X + 1) as factors, we can use the fact that if a polynomial has these factors, it can be expressed as a product of these two binomials multiplied by some constant. First, we find the product of the two factors: (3X - 5)(4X + 1) = 12X² + 3X - 20X - 5 This simplifies to: 12X² - 17X - 5 Now we look back at the options provided. The polynomial in the first choice, 12X² - 17X - 5, matches exactly with the expression we obtained from factoring (3X - 5) and (4X + 1). This confirms that this polynomial indeed has both (3X - 5) and (4X + 1) as factors. Polynomials B, C, and D do not yield this combination of factors when evaluated, as they do not align with the derived expression. Thus, the correct polynomial that has (3X - 5) and (4X + 1) as factors is 12X² - 17X
