If a^1/2 + b^1/2 - c^1/2= 0 find (a+b-c)^2

a½+b½-c½=0

a½+b½=c½

Squaring on both sides,

(a½+b½) ²=c½×²

a+b+2a½b½=c

a+b-c= -2a½b½

Again squaring on both sides,

(a+b-c) ²=(-2a½b½) ²

= 4ab.

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
