Now check both solutions by substituting them into the original equation. Take a look at this next problem that demonstrates a potential pitfall of squaring both sides to problem solving involving radical expressions the radical. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world’s best and brightest mathematical minds have belonged to autodidacts.
