Multiplication of Polynomials

Question 15 • [INMT3] Integrated Math 3 Sem 1 (26-27)

Multiply.(2x2 + 4x - 3)(x2 - 2x + 5)

Answer
A
2x4 + 7x2 - 15
B
2x4 - 8x2 - 15
C
2x4 - x2 + 26x - 15
D
2x4 + 8x3 - x2 + 26x - 15

Explanation

Distribute each term: (2x² + 4x − 3)(x² − 2x + 5) = 2x⁴ − 4x³ + 10x² + 4x³ − 8x² + 20x − 3x² + 6x − 15. Combining like terms cancels the x³ terms and gives 2x⁴ − x² + 26x − 15, which is choice C.
