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.
Answer:
<u>8</u>
Step-by-step explanation:
Now consider an experiment of tossing three coins simultaneously. The possible outcomes will be HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. So the total number of outcomes is 23 = <u>8</u>.
Answer:
In x-axis: 
, In y-axis: 
Step-by-step explanation:
The rule of the reflection of a point across the x-axis is as shown:
The reflection of the point 
across the x-axis is given by 
.
The point given to us is 
, when reflected across the x-axis we get:
Now, when a point is reflected across the y-axis we get the point 
.
So when the point is reflected across the y-axis we get: 
.
Answer:
59 degrees
Step-by-step explanation:
If BCG is 40 degrees and AGC is 19 degrees, you would add the 2 angles to find AGB giving you 59 degrees.
