the value would be 2x10^7
Answer: The correct option is (c)
Step-by-step explanation: We are given to solve the following quadratic equation by the method of completing the square:
Also, we are to find the constant added on both sides to form the perfect square trinomial.
We have from equation (i) that
So,
Thus, the required solution is and the value of the constant added is
Option (c) is correct.
91 / 7
7 fits within 9 only once, so the first number is 1
you have two left over
drop the one from 91 down, so you have to figure out how many times 7 goes into 21
it goes in 3 times
so the answer is 13

29 - 82
since 82 is bigger than 29, you will be getting a negative number.
if you did 82 - 29 it would be 53
but after you hit zero, it is 52 below zero, so the answer is -53
