A list of 5 steps Cecile used to factor 16 x squared minus 9. Analyze Cecile’s work. Is it correct? No, adding in 0x keeps an equivalent polynomial. No, she did not fill in the X correctly. She should have 16 on top and –9 on the bottom. No, 16x6 12x3 – 12x3 – 9 is not equivalent to 16x6 – 9. Yes, Cecile factored the polynomial correctly.

Respuesta :

The Cecile factored the polynomial correctly by factor 16 x squared minus 9 using the X-method of factorization.

What is factor of polynomial?

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,

[tex]f(x)=16x^6-9[/tex]

Now, Cecile add 0x as,

[tex]f(x)=16x^6+0x-9[/tex]

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,

[tex]f(x)=16x^6+12x-12x-9\\f(x)=4x^3(4x^3+3)+(-3)(4x^3+3)\\f(x)=(4x^3+3)(4x^3-3)[/tex]

Thus, the Cecile factored the polynomial correctly by factor 16 x squared minus 9 using the X-method of factorization.
