Solving Radical Functions/Equations
no solution, answer is extraneous
Solve. Be sure to check for extraneous solutions. 2+√x = 0
x=3
Solve. Be sure to check for extraneous solutions. 6-√(x + 1) = 4
x=101/2
Solve. Be sure to check for extraneous solutions. √(2x - 1) = 10
x=17
Solve. Be sure to check for extraneous solutions. √(2x- 9) + 10 = 15
x=53/2
Solve. Be sure to check for extraneous solutions. √(4x-6)=10
x=-18
Solve. Be sure to check for extraneous solutions. √-2x - 6 = 0
x=16
Solve. Be sure to check for extraneous solutions. √x + 6 =10
x=44
Solve. Be sure to check for extraneous solutions. (Think what's the opposite of taking the 4th root)
x=67
Solve. Be sure to check for extraneous solutions. Think what's the opposite of cube rooting.
squaring the value
The opposite of taking a square root is:
