WebAlgebra. Solve for a c = square root of a^2+b^2. c = √a2 + b2 c = a 2 + b 2. Rewrite the equation as √a2 +b2 = c a 2 + b 2 = c. √a2 +b2 = c a 2 + b 2 = c. To remove the radical on the left side of the equation, square both sides of the equation. √a2 +b22 = c2 a 2 + b 2 2 = c 2. Simplify each side of the equation. primary school finder nsw
