Answer:
![x^{\frac{2}{3} }](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
Step-by-step explanation:
⇒ ![x^({\frac{4+2}{3}) } ^{\frac{1}{3} }](https://tex.z-dn.net/?f=x%5E%28%7B%5Cfrac%7B4%2B2%7D%7B3%7D%29%20%7D%20%5E%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
⇒ ![(x^{\frac{6}{3} })](https://tex.z-dn.net/?f=%28x%5E%7B%5Cfrac%7B6%7D%7B3%7D%20%7D%29)
⇒ ![(x^{2} )\frac{1}{3}](https://tex.z-dn.net/?f=%28x%5E%7B2%7D%20%29%5Cfrac%7B1%7D%7B3%7D)
⇒ ![x^{\frac{2}{3} }](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B2%7D%7B3%7D%20%7D)
Ok, so the quadratic coefient is 1, so great
take 1/2 of the linear coefient and square it
10/2=5, (5)^2=25
add that to both sides
x^2+10x+25=7+25
factor perfect square trionomial
(x+5)^2=32
squaer root both sides
x+5=+/-4√2
minus 5
x=-5+/-4√2
x=-5+4√2 and -5-4√2
Answer:
No, it cannot make a triangle
12.
It is easy all you have to do is 15-3 because 1+2=3
