sqrt%2812x%5E5%29-sqrt%2818x%29-sqrt%28300x%5E5%29%2Bsqrt%2898x%29 Start with the given expression


2x%5E2%2Asqrt%283x%29-sqrt%2818x%29-sqrt%28300x%5E5%29%2Bsqrt%2898x%29 Simplify sqrt%2812x%5E5%29 to get 2x%5E2%2Asqrt%283x%29


2x%5E2%2Asqrt%283x%29-3%2Asqrt%282x%29-sqrt%28300x%5E5%29%2Bsqrt%2898x%29 Simplify sqrt%2818x%29 to get 3%2Asqrt%282x%29


2x%5E2%2Asqrt%283x%29-3%2Asqrt%282x%29-10x%5E2%2Asqrt%283x%29%2Bsqrt%2898x%29 Simplify sqrt%28300x%5E5%29 to get 10x%5E2%2Asqrt%283x%29


2x%5E2%2Asqrt%283x%29-3%2Asqrt%282x%29-10x%5E2%2Asqrt%283x%29%2B7%2Asqrt%282x%29 Simplify sqrt%2898x%29 to get 7%2Asqrt%282x%29


-8x%5E2%2Asqrt%283x%29%2B4%2Asqrt%282x%29 Combine like terms.
