Which equation results from isolating a radical term and squaring both sides of the equation for the equation √(c-2)-√c=5?

C-2 = 25+

c-2= 25-c

C-2 = 25+c-1076

C-2 25+C+10

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

#12 the answer is the third option
