b2 + a2 = c2

pb2 + a2 = pc2

b + a = c

a = c-b

Explain the mistake(s) made by the student and provide the correct solution.

**Steve**, Wednesday, July 9, 2014 at 4:11pmp? do you mean √?

√(b^2+a^2) = √c^2

clearly the next step is flawed.

√(b^2+a^2) ≠ b+a

while √(b^2*a^2) = √b^2 * √a^2,

√(b^2+a^2) ≠ √b^2 + √a^2

I figure you can take it from there

a^2=c^2-b^2

a=square root of (c^2-b^2)
