For questions 810, use the radical equation:
radical x2 = 5
8. squaring both sides will yield
a)x – 2 = 25
b)x – 2 = 5
c) x – 4 = 25
d) x2 – 4 = 25
9. The correct solution to the radical equation is:
a) 3
b) 21
c) 27
d)29
10. Squaring both sides of the equation to remove the radicand first:
a)Is always the best first step
b) Can sometimes cause the problem to look more difficult
c)Can always make the problem more difficult
d) None of the above
