It looks Ok if that's actually your problem
The problem must be to simplify the expression
+3%2Asqrt%287%29+-+2%2Asqrt%2828%29+-+2%2Asqrt%282%29+%2B+8%2Asqrt%2818%29+

+3%2Asqrt%287%29+-+2%2A2%2Asqrt%287%29+-+2%2Asqrt%282%29+%2B+8%2A3%2Asqrt%282%29+
+3%2Asqrt%287%29+-+4%2Asqrt%287%29+-+2%2Asqrt%282%29+%2B+24%2Asqrt%282%29+
+sqrt%287%29%2A%28+3+-+4+%29+%2B+sqrt%282%29%2A%28+24+-+2+%29+
+22%2Asqrt%282%29+-+sqrt%287%29+
