To find the x-intercepts, we set y equal to zero:

15x² - 7x - 2 = 0

Now, we look for two numbers whose product is the product of the coefficient of x² (15) and the constant term (-2), which is -30, and whose sum is the coefficient of x (-7). In this case, the numbers are -10 and 3:

15x² - 10x + 3x - 2 = 0

Now, we group the terms accordingly and factor by grouping:

(15x² - 10x) + (3x - 2) = 0

5x(3...
