SOLUTION: A student is asked to solve b2 + x2 = a2 and gives the following solution. b2 + x2 = a2 sqrt(b2 + x2) = sqrt(a2) b + x = a x = a − b Find the multiple mistakes the stude

Question 472212: A student is asked to solve b2 + x2 = a2 and gives the following solution.
b2 + x2 = a2
sqrt(b2 + x2) = sqrt(a2)
b + x = a
x = a − b
Find the multiple mistakes the student made and explain why they are incorrect
**sqrt = square root
