Question

For questions 8-10, use the radical equation:

radical x-2 = 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

Answer 1

\[\sqrt{x-2}=5\]?

Answer 2

yes

Answer 3

\[(\sqrt{x-2})^2=5^2\]

Answer 4

x-2=25
x= 25+2
x= 27

Answer 5

?

Answer 6

so its a?

Answer 7

8)a
9)c

Answer 8

10)a Squaring both sides of the equation to remove the radicand first:

Answer 9
