In completing the square method, considering the equation X^2 - 2x + the number to be added should be<u> 1 </u>to make it a perfect square
<h3>How to know term that should added</h3>
The standard quadratic equation is of the form
ax^2 + bx + c
The completing the square method is one of the methods of solving quadratic equations
The factor to be added to the equation while using the completing the square method is of the formula
(b / 2a)^2
compared to the equation in the problem X^2 - 2x +
= (b / 2a)^2
= (2 / 2)^2
= (1)^2
= 1

Answer:
It takes them 7minutes to finish 50env
Step-by-step explanation:
We know that jerry can stuff 7 in 2min and tom can do 4 per min, so 8 for every 2min.
So 8+7=15env for every 2min 7.5/min
15+15=30+15=45
50=15x/2 50*2=15x 100=15x 100/15=x x=6.67 then rounded it to 7min
