Could someone please help me with this.

Assume nonnegative and simplify.

v45 + v80 - 3 v20

I couldn't figure out how to insert the radical sign so the v represents the radical sign.

(3v5 + v3)(v2 + 2v5)

(v3+ 4v7)2square

ans=root of 5

sqrt45 + sqrt80 - 3 sqrt20

sqrt9*5 + sqrt16*5 - 3 sqrt4*5

3sqrt5+ 4sqrt5-6sqrt5 then combine

(3v5 + v3)(v2 + 2v5)

3v10 + 6v25 + v6 + 2v15

you can combine some, the sqrt 5 appears in three terms.

x-1=3
