Answer: B
Explanation:
Distribute
(2x + 1)(x² - 4x+5)
2x(x²- 4x+5) + 1(x² -4+5)
Distribute
2x(x²-4x+5)+ 1(x² - 4x+5
2x³ - 8x² + 10x + 1(x² -4x+5)
Multiply by 1
2x³ -8x² + 10x + 1(x² -4x+5)
2x³ - 8x² + 10x + x² - 4x + 5
Combine like terms
2x³ - 8x² + 10x + x² -4x+5
2x³-7x² + 10x - 4x + 5
Combine like terms
2x³- 7x² + 10x-4x + 5
2x³-7x² + 6x+5
Therefor, it's 2x³ - 7x²+6x+5 Hope this helps stay safe :)
