Step-by-step explanation:
Answer: -2, 0, 4
Set the equation equal to zero.
x³ - 2x² - 8x = 0
Factor out x in the equation, since all the terms (x³, -2x², and -8x) are divisible by x. You can check your accuracy using the Distributive Property.
x(x² - 2x - 8) = 0
Factor out the polynomial. To do this, find two numbers that multiply to get the last term, -8, and add together to get the middle term, -2. In this case, those two numbers are -4 and 2 (-4 × 2 = -8 and -4 + 2 = -2). Don't forget about the x that was factored out before!
x(x - 4)(x + 2) = 0
Set each factor equal to zero and solve for x. The factors in the equation are x, (x - 4), and (x + 2).
x = 4
x = -2
The zeros of the polynomial function are -2, 0, and 4.
Assuming you need to solve for x:
-6(x + 6) - 10 = -2(5 + 4x)
start by distributing your numbers outside the front of your parentheses:
-6x - 36 - 10 = -10 - 8x
then combine like terms:
-6x - 46 = -10 - 8x ... add 10 to both sides (which technically could have cancelled out in the step prior, but regardless)
-6x - 36 = -8x ... add 6x to both sides
-36 = -2x ... divide both sides by -2
x = 18
