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.
