(x^3−7x−6) : (x−4)<br> Kan someone solve this for me, and show how to get it?

Vladimir79 [104]

Answer:

x = 3 or x = -1 or x = -2

Step-by-step explanation:

Solve for x:

(x^3 - 7 x - 6)/(x - 4) = 0

Hint: | Multiply both sides by a polynomial to clear fractions.

Multiply both sides by x - 4:

x^3 - 7 x - 6 = 0

Hint: | Factor the left hand side.

The left hand side factors into a product with three terms:

(x - 3) (x + 1) (x + 2) = 0

Hint: | Find the roots of each term in the product separately.

Split into three equations:

x - 3 = 0 or x + 1 = 0 or x + 2 = 0

Hint: | Look at the first equation: Solve for x.

Add 3 to both sides:

x = 3 or x + 1 = 0 or x + 2 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 1 from both sides:

x = 3 or x = -1 or x + 2 = 0

Hint: | Look at the third equation: Solve for x.

Subtract 2 from both sides:

Answer: x = 3 or x = -1 or x = -2

You are traveling 160 miles and it takes you 2.5 hours to get there what was your average speed

Anna35 [415]

The speed is 64 miles per hour

Step-by-step explanation:

Lets define speed first.

"Speed is the distance per unit time"

Speed is denoted by s.

Given

Distance = d = 160 miles

Time = t = 2.5 hours

$Speed = \frac{Distance}{Time}\\s = \frac{d}{t}\\\\s = \frac{160}{2.5}\\\\s = 64\ miles\ per\ hour$

Hence,

The speed is 64 miles per hour
