Answer:

2

Step-by-step explanation:

2x^2 - 4x + n = 0 has only one solution when it can be represented as:

a(x-b)^2 = 0

Let us begin by factoring  out the 2 we are left with:

2(x^2 - 2x + m) = 0 where 2 * m = n

Now x^2- 2x + m can be represented as (x-a)(x-b) where a + b = 2 and m = a * b

We want a = b and a + b = 2 so a = b = 1

Hence m = 1

So 2(x^2 - 2x + 1) = 0

So 2x^2 - 4x + 2 = 0

Hence n = 2

Solve the inequality if possible 4(3-2x)>2(6-4x)
GenaCL600 [577]

Final Answer: No Solution

Steps/Reasons/Explanation:

Question: 4(3-  2x) > 2(6-  4x)

<u>Step 1</u>: Divide both sides by 2.

2(3 - 2x) > 6 - 4x

<u>Step 2</u>: Expand.

6 - 4x > 6 - 4x

<u>Step 3</u>: Since 6 - 4x > 6 - 4x is false, we have no solution.

No Solution
