Complete the SquareSolve for x over the real numbers:(x - 8)^2 - 100 = 0
Add 100 to both sides:(x - 8)^2 = 100
Take the square root of both sides:x - 8 = 10 or x - 8 = -10
Add 8 to both sides:x = 18 or x - 8 = -10
Add 8 to both sides:Answer: x = 18 or x = -2
Answer:

Step-by-step explanation:
Javier did not raise the coefficients to the third power
When Javier raised to the third power, he wrote that , but it equals .
In the last step, Javier divided the exponents. He should have used the quotient of powers property and subtracted them.

Step-by-step explanation:
Remember that when you want to solve a problem like this, you express the equation as following
So, if you know the inverse of then
For this case
Now for this case the inverse of A would be
Then when you multiply with the vector solution
So from that information you can conclude that the solution to the system of equations is x = 500/7 y = 2400/7 and z = 2700/7
