The first three steps of completing the square to solve the quadratic equation x2 +4x-6=0

hodyreva [135]

Answer:

Step-by-step explanation:

1. Move the 6 to the other side: x^2 +4x =6

2. Square half the coefficient of the x term: (4/2)^2 = 4

3. Add this 4, and then subtract this 4, from x^2 + 4x:

x^2 +4x + 4 - 4 =6

4. Rewrite this perfect square as the square of a binomial:

(x + 2)^2 - 4 = 6

5. Add 4 to both sides: (x + 2)^2 = 10

6. Find the sqrt of both sides: x + 2 = √

Find the modulus of the complex number 6-2i

Papessa [141]

Answer:

The modulus of the complex number 6-2i is:

$|z|\:=2\sqrt{10}$

Step-by-step explanation:

Given the number

$6-2i$

We know that

$z = x + iy$

where x and y are real and $\sqrt{-1}=i$

The modulus or absolute value of z is:

$|z|\:=\sqrt{x^2+y^2}$

Therefore, the modulus of $6-2i$ will be:

$z=6-2i$

$z=6+(-2)i$

$|z|\:=\sqrt{x^2+y^2}$

$|z|\:=\sqrt{6^2+\left(-2\right)^2}$

$=\sqrt{6^2+2^2}$

$=\sqrt{36+4}$

$=\sqrt{40}$

$=\sqrt{2^2}\sqrt{2\cdot \:5}$

$=2\sqrt{2\cdot \:5}$

$=2\sqrt{10}$

Therefore, the modulus of the complex number 6-2i is:

$|z|\:=2\sqrt{10}$
