ALGEBRA 1

change 50 to 25*2
sqrt 50 = 5 sqrt2

change 8 to 4*2

Nope:
(sqrt3-sqrt5)(sqrt3-sqrt5).
remember
(a-b)(a-b)= a^2-2ab + b^2

Simplify.Express in simpliest radical form.
1.3sqrt2 +sqrt50
Cannot be solve. Terms have unlike radicals

2.3sqrt8+2 sqrt16
Terms have unlike radicals

3. Not sure how to do this one as there is no example in my text to follow
(sqrt3-sqrt5)(sqrt3-sqrt5).
I guess the answer as 1


SO MY ANSWER TO #1 would be 8sqrt2

Here is what I have done with the #2
3SQRT4*2 +2 SQRT4.What Am i doing with the 4*2. I KNOW I CAN NOW ADD THE 3 AND THE 2 TO MAKE THAT 5. BUT WHAT ABOUT THE 2 NEXT TO THE 4. tHANKS FOR YOUR KIND HELP
