Simplify ( √2 + √3 )(√2 - √3 ) ÷ √3 (√3 - 2√48 )
1) Factor √48 as √4*4*3
2) Write that as 2*2√3
Same as 4√3
Now the expression says
( √2 + √3 )(√2 - √3 ) ÷ √3 (√3 - 8√3 )
2) Multiply ( √2 + √3 )(√2 - √3 )
When you do, you bring back the original binomial (a Difference of Two Squares)
2 - 3
2 - 3 ÷ √3 (√3 - 8√3 )
3) Clear the parentheses by distributing the √3 coefficient
2 - 3 ÷ 3 - 8*3
Same as 2 - 3 ÷ 3 - 24
4) Compute the numbers
- 1 ÷ - 21
Same as
1 / 21 <-- answer
1/21
