%288%2Bsqrt%28+3%29%29%288-+sqrt%28+3%29%29 Start with the given expression



8%2A8-8%2Asqrt%28+3%29%2B8%2Asqrt%28+3%29-sqrt%28+3%29sqrt%28+3%29 Foil



8%2A8%2Bcross%28-8%2Asqrt%28+3%29%2B8%2Asqrt%28+3%29%29-sqrt%28+3%29sqrt%28+3%29 Notice the terms 8sqrt%283%29 and -8sqrt%283%29 add and cancel out to zero



64-3 Multiply 8*8 to get 64. Multiply sqrt%283%29sqrt%283%29 to get 3
