Question 39245: Explain the process and show EACH step in the process of simplifying the following problems:
a.(sqrt2 + 5)(sqrt2 - 3)
b. sqrt5/sqrt8
c. (6 - sqrt20)/2
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
a.(sqrt2 + 5)(sqrt2 - 3)
Use FOIL to get:
2+2sqrt2-15
=2sqrt2 - 13
b. sqrt5/sqrt8
Multiply numerator and denominator by sqrt2 to get:
sqrt(10)/4
c. (6 - sqrt20)/2
Divide each term be "2" to get:
3 - sqrt(5)
