sqrt%2812%29-sqrt%2850%29%2Bsqrt%2872%29 You can only add radicals with the same index, so let's simplify, find factors that are perfect squares:
sqrt%284%29%2Asqrt%283%29-sqrt%2825%29%2Asqrt%282%29%2Bsqrt%2836%29%2Asqrt%282%29 Take the square roots of the perfect squares
2sqrt%283%29-5sqrt%282%29%2B6sqrt%282%29 Combine the numbers with like radicals.
2sqrt%283%29%2Bsqrt%282%29
