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!)

k = 12

Step-by-step explanation:

Given:

The equation

To find:

Value of 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: to have one distinct solution:

Here,

a = 2,

b = -k and

c = 18

Putting the values, we get:

The equation becomes:

And the one root is:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
