Given:
The equation is:
To find:
The error in the given equation and correct it.
Solution:
We have,
Taking left-hand side, we get
![[\because a^2-b^2=(a-b)(a+b)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29%5D)
![[\because (ab)^x=a^xb^x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28ab%29%5Ex%3Da%5Exb%5Ex%5D)
It is not equal to right-hand side 
. In the right hand side, there must be a negative sign instead of positive sign.
Therefore, 
.
The correct result would be y = -6/5 - (2 * sqrt(6))/5 and<span> y = (2 * sqrt(6))/5 - 6/5.

Answer: 15x^2+6x-20
Step-by-step explanation:
use symbolab.com for calculator and further steps
d/dx (5x+3)5
((x-2)(x+2))=2x
5(x-2)(x+2)+2x(5x+3)
15x^2=6x-20
Answer:
the anwser is H
Step-by-step explanation:
- frist x^2=16 it means the radical of 16 is x
the radical of 16 is《 4》
♧x^3 it means 4^3=64
the radical of 4 is 2
- then 64+2=66
