Question

one of the factor of 6x² - x-15 is (2x + 3) .find the other factor ​

Answer 1

Step-by-step explanation:

$6 {x}^{2} - x - 15 = 0 \\ 6 {x}^{2} + 9x - 10x - 15 = 0 \\ 3x(2x + 3) - 5(2x + 3) = 0 \\ (2x + 3)(3x - 5) = 0$

therefore the other factor is 3x - 5

other method

$\frac{6 {x}^{2} - x - 15 }{2x + 3} \\ = 3x - 5$

hope you get your answer
