Hello!
![\bf 5 \sqrt{37} + \sqrt{98} - 3 \sqrt{147}](https://tex.z-dn.net/?f=%20%5Cbf%205%20%5Csqrt%7B37%7D%20%20%2B%20%20%5Csqrt%7B98%7D%20%20-%203%20%5Csqrt%7B147%7D%20)
![\bf 5 \sqrt{37} + 7 \sqrt{2} - 21 \sqrt{3}](https://tex.z-dn.net/?f=%20%5Cbf%205%20%5Csqrt%7B37%7D%20%20%2B%207%20%5Csqrt%7B2%7D%20%20-%2021%20%5Csqrt%7B3%7D%20)
I removed the factors from under the radical.
Good luck! :)

<span>-5n + 15 is the answer I think
I understand if it's not</span>
Q1. The answer is <span>(x – 14)(x + 14)
</span>
x² - 196 = x² - 14²
a² - b² = (a - b)(a + b)
a = x, b = 14
x² - 196 = x² - 14² = (x - 14)(x + 14)
Q2. The answer is (3x - 8)(3x + 8)
9x² - 64 = (3x)² - 8²
a² - b² = (a - b)(a + b)
a = 3x, b = 8
9x² - 64 = (3x)² - 8² = (3x - 8)(3x + 8)
Q3. The answer is (7x - 4)²
49x² - 56x + 16 = (7x)² - 2 * 7x * 4 + 4²
(a - b)² = a² - 2ab + b²
a = 7x, b = 4
49x² - 56x + 16 = (7x)² - 2 * 7x * 4 + 4² = (7x - 4)²
