Answer:

x=1+2i/2

Using the method of completing the square

(2x)²-2(2x)1 +(1)²+4=0

(2x-1)²=-4

taking square root on both sides

2x-1=2i

2x=1+2i

x=1+2i/2

gizmo_the_mogwai [7]

Answer:

Dividing 7,040 by 3 using long division method it gives the quotient  <u>2346</u> and the remainder <u>2</u>.

Step-by-step explanation:

Given:

7,040 divide by 3 using long division.

Now, to divide using long division method:

Step 1: Divide 7 by 3. 3 x 2 =6.

So, 1 will be remainder.

Step 2: Bring 0 down next to 1. So, now the new number is 10 .

Divide 10 by 3. 3 x 3 = 9.

Remainder is 1

So, quotient  is 23 till now.

Step 3: Bring 4 down next to 1. The number is now 14.

Divide 14 by 3. 3 x 4 = 12.

Thus, remainder is 2.

Step 4: Bring 0 next to 2. Getting the new number 20.

So, divide 20 by 3. 3 x 6 = 18.

Thus, the remainder is 2.

So, the quotient is 2346.

And the remainder is 2.

Therefore, dividing 7,040 by 3 using long division method it gives the quotient 2346 and the remainder 2.
