Give answer and show work.
For the equation x - 2 鈭歺 = 0, perform the following: solve for all values of x that satisfies the equationconcert venue
x - 2rtx = 0
Add 2rtx to both sides
x = 2rtx
Divide both sides by 2
x/2 = rtx
To get rid of the square root, square both sides.
x^2 / 4 = x
Multiply by 4.
x^2 = 4x
Subtract 4x from both sides to get the equation equal to zero.
x^2 - 4x = 0
Factor out an x
x(x-4) = 0
Set each factor equal to zero and solve for x.
x = 0 and x-4 = 0
Hope this helps. Good Luck.
For the equation x - 2 鈭歺 = 0, perform the following: solve for all values of x that satisfies the equationevents opera theater
set x = 2* x^1/2 to solve
square both sides to get: x^2 = 4x
The only answer that works here is x=4
x= 4
x = 2鈭歺
x2 = 4x
x2 - 4x = 0
x(x-4) = 0
x = 0
x = 4
x - 2 鈭歺 = 0
x = 2 鈭歺
Square both sides
x^2 = 4x
x^2 - 4x = 0
x(x - 4) = 0
x = 0, x = 4
When you square both sides of an equation, you might introduce a redundant root, so check all the results in the original equation
0 - 2鈭? = 0
0 = 0
4 - 2鈭? = 0
4 - 2*2 = 0
0 = 0
Hopefully I did it right.
x - square root of x = 0....original equation
x = square root of x......plus square of x on both sides
x = {0,1}
0*0=0 0's square root is 0
1*1=1 1's square root is 1
Square root is use for numbers like x^2, y^2. So the only numbers that has the same value even it's multiplied on itself are 0 and 1 only. By the way, even though (-1) * (-1) =1, but it may not work in this equation.
x - 2 鈭歺 = 0
x=2鈭歺
x^2=4x
x=4
