Answer:
To factor 4x³-10x²-14x, we can first factor out the greatest common factor, which is 2x:
4x³-10x²-14x = 2x(2x² - 5x - 7)
Next, we can factor the quadratic expression 2x² - 5x - 7 using either factoring by grouping, completing the square, or the quadratic formula. Here, we'll use factoring by grouping:
2x² - 5x - 7 = 2x² - 7x + 2x - 7
= (2x² - 7x) + (2x - 7)
= x(2x - 7) + (2x - 7)
= (2x - 7)(x + 1)
Therefore, the factored form of 4x³-10x²-14x is:
4x³-10x²-14x = 2x(2x - 7)(x + 1)
