Identify the vertical asymptotes of <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E3-16x%7D%7B-3x%5E2%2B3x%2B18%7D" id="TexForm

navik [9.2K]

$\sf \frac{ {x}^{3} - 16x}{ { - 3x}^{2} + 3x + 18 }$

To find the vertical asymptotes set denominator as 0

$\sf - 3x ^{2} + 3x + 18 = 0$

Divide both sides of the equation by-3

$\sf \: {x}^{2} - x - 6 = 0$

Write -x as a difference

$\sf \: {x}^{2} + 2x - 3x - 6= 0$

Factor out x from the expression

$\sf \: x \times (x + 2) - 3x - 6 = 0$

Factor out -3 from the expression

$\sf \: x \times (x + 2) - 3(x + 2) = 0$

Factor out x+2 from the expression

$\sf(x + 2)(x - 3) = 0$

When the product of factors equals 0, at least one factor is 0

$\sf \: x + 2 = 0 \\ \sf \: x - 3 = 0$

Solve the equations for x

$\sf \: x = - 2 \\ \sf \: x = 3$

Q = x^2 - 15x + 56 = 0

Dominik [7]

Answer:

x = 8

x = 7

Step-by-step explanation:

Solving x2-15x+56 = 0 by the Quadratic Formula .

According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :

- B ± √ B2-4AC

x = ————————

In our case, A = 1

B = -15

C = 56

Accordingly, B2 - 4AC =

225 - 224 =

Applying the quadratic formula :

15 ± √ 1

x = —————

So now we are looking at:

x = ( 15 ± 1) / 2

Two real solutions:

x =(15+√1)/2= 8.000

or:

x =(15-√1)/2= 7.000
