Answer:

$\tt x=\pm5\sqrt{2}$

Step-by-step explanation:

$\tt x^2 - 25 = 25$

$\tt x^2-25+25=25+25$ (Add 25 to both sides)

$\tt x^2=50$ ( Take square of both sides)

$\tt x=x=\sqrt{50},\:x=-\sqrt{50}$

$\tt x=\pm5\sqrt{2}$

What is the solution set for

Mumz [18]

Answer: C. (-3, 9)

Step-by-step explanation:

Given

2|x-3|=12

Divide both sides by 2

2|x-3|/2=12/2

|x-3|=6

Take of absolute value sign (REMEMBER need to take into consideration of two conditions)

x-3=±6

1)x-3=6

x=9

2)x-3=-6

x=-3

**NOTE**: need to check each solution whether or not they are suitable

Hope this helps!! :)

The complex numbers corresponding to the endpoints of one diagonal of a square drawn on a complex plane are 1 + 2i and -2 – i.

kodGreya [7K]

Technically the endpoints will be intersection of first endpoint between x=1 and y=-1second endpoint between x=-2 and y=2
so they are 1-i and -2+2i
