    yes. first look at the x's to see if you can pull out a common factor. Your lowest exponent is 3, so factor out x³ first

    yes. Then we need to factor 8x² - 22x + 15 To do that multiply 8 and 15 to get 120 You need to find 2 numbers that multiply to 120 and add to -22

    you have -22 so -10 and -12. The way I do it is just to divide them both by 8 (since that's the front number) and then reduce. |dw:1435792249711:dw|
