Answer: ![-10\sqrt{2}](https://tex.z-dn.net/?f=-10%5Csqrt%7B2%7D)
<u>Step-by-step explanation:</u>
![7\sqrt{32} - 6\sqrt{72}](https://tex.z-dn.net/?f=7%5Csqrt%7B32%7D%20-%206%5Csqrt%7B72%7D)
= ![7\sqrt{(2*2)*(2*2)*2} - 6\sqrt{(2*2)*2*(3*3)}](https://tex.z-dn.net/?f=7%5Csqrt%7B%282%2A2%29%2A%282%2A2%29%2A2%7D%20-%206%5Csqrt%7B%282%2A2%29%2A2%2A%283%2A3%29%7D)
= ![7*2*2\sqrt{2} - 6*2*3\sqrt{2}](https://tex.z-dn.net/?f=7%2A2%2A2%5Csqrt%7B2%7D%20-%206%2A2%2A3%5Csqrt%7B2%7D)
= ![28\sqrt{2} - 36\sqrt{2}](https://tex.z-dn.net/?f=28%5Csqrt%7B2%7D%20-%2036%5Csqrt%7B2%7D)
Now that they have the same radical, we can subtract their coefficents
= ![(28 - 36)\sqrt{2}](https://tex.z-dn.net/?f=%2828%20-%2036%29%5Csqrt%7B2%7D)
= ![-8\sqrt{2}](https://tex.z-dn.net/?f=-8%5Csqrt%7B2%7D)
