Answer:

x = -7 and x = 5

Explanation:

First, make the problem easier by taking out the common factor (6).

6x² - 12x - 210 -----> 6(x² - 2x - 35)

What two numbers multiply to -35 and add to -2? These two numbers are -7 and 5. You can now write the factored form of the expression.

6(x² - 2x - 35) -----> 6(x - 7)(x + 5)

Finally, find the x's by making each term with x equal to zero.

x + 7 = 0 -----> x = -7

x - 5 = 0 -----> x = 5

The x's are x = -7 and x = 5
