The function Q(x)=2x^2-kx+18. For what value of k does Q(x) have one distinct real solution? (NEEDS TO BE DONE WITHIN 2 HOURS!)
Aliun [14]

Answer:

k = 12

Step-by-step explanation:

Given:

The equation Q(x)=2x^2-kx+18

To find:

Value of k = ? for which the given equation has one distinct real solution.

Solution:

The given equation is a quadratic equation.

There are always two solutions of a quadratic equation.

For the equation: ax^{2} +bx+c=0 to have one distinct solution:

b^2 - 4ac = 0

Here,

a = 2,

b = -k and

c = 18

Putting the values, we get:

(-k)^2 - 4\times 2\times 18 = 0\\\Rightarrow k^2 = 18\times 8\\\Rightarrow k^2 =144\\\Rightarrow k = 12

The equation becomes:

Q(x)=2x^2-12x+18

And the one root is:

2(x^2-6x+9 ) = 0\\\Rightarrow 2(x-3)^2=0\\\Rightarrow x = 3

Hitman42 [59]
A 
coefficient = 10.50 or 15, both real numbers that qualify variables 
variable = c and h 
constant = 50 

B 
10.50h + 15c + 50 
10.5 x 37 + 15 x 12 + 50 
388.50 + 180 + 50 = 618.50 

C 
Coefficient would change from 10.50 to 11.25 
<span>It is fixed until the next raise.

I hope my answer has come to your help. God bless and have a nice day ahead!</span>
