Answer: .
Step-by-step explanation:
The mid point (x,y) of the line joining the points (a,b) and (c,d) is given by :-
Let the midpoint of the segment joining points (a, b) and (j, k) be (x,y).
On the same criteria, the midpoint of the segment joining points (a, b) and (j, k) is given by :-
Which can be written as
Hence, the correct option is .
The Cecile factored the polynomial correctly by factor 16 x squared minus 9 using the X-method of factorization.
<h3>What is factor of polynomial?</h3>Factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.
The given polynomial expression is,
Now, Cecile add 0x as,
Now, here the product of 16 and 9 is 144. Therefore, the factors must have the product of 144 and sum of 0. Thus, by using the split the factor method as,
Thus, the Cecile factored the polynomial correctly by factor 16 x squared minus 9 using the X-method of factorization.
