Step-by-step explanation:

$third \: term = ( \frac{1}{2} \times coefficient\: of \:x)^{2} \\ \\ = ( \frac{1}{2} \times \frac{ - 2}{7} )^{2} \\ \\ = ( \frac{ - 1}{7} )^{2} \\ \\ = \frac{1}{49}$

So, you need to add $\frac{1}{49}$ on both sides of the quadratic equation.

Find the multiplicative inverse of -2 in mod 7<br>

Elis [28]

Answer:

So something mod 7 is -2
Lets consider what mod does as a commands: If you have 7 and then mod it by 2 ie 7%2 you get 1
Essentially mod is seeing how many times a # goes into the other number and finding the remainder.
In this case we want the remainder of 2: -8%3 =-2
note there is also a mathematical procedural way to solve this.
