Well, you can't just add the term as they are, you must first simplify them before you can add them.
4%2Asqrt%2832%29%2B5%2Asqrt%2872%29+=+4%2Asqrt%2816%2A2%29%2B5%2Asqrt%2836%2A2%29=4%2Asqrt%2816%29%2Asqrt%282%29%2B5%2Asqrt%2836%29%2Asqrt%282%29=4%2A4%2Asqrt%282%29%2B5%2A6%2Asqrt%282%29+=+16%2Asqrt%282%29%2B30%2Asqrt%282%29=46%2Asqrt%282%29
