Search on the internet and you will get the answer

<u>Let us assume that:</u>

We can also write it as:

Squaring both sides, we get:


By splitting the middle term:



<u>Therefore:</u>


<u>But x cannot be negative. </u>

Therefore, the value of the expression is 3.

Given:

We can also write it as:

_____
Combining like terms in the given expression makes it simplify to ...
(2x -18x) +(14y) +(9 -10) = -16x +14y -1
We are to compare this expression with the offered expressions to see if they simplify to the same thing. We'll examine those left-to-right starting with the top row:
- 2x -18x +14y -19 = -16x +14y -19 . . . not the same
- -2xy -1 . . . not the same
- 16x +14y -1 . . . not the same
- 9 -16x +14y -10 = -16x +14y -1 . . . equivalent
- -16x +14y -1 . . . equivalent and simplified
- 2x -18x +14y -1 = -16x +14y -1 . . . equivalent
