The polynomial x3 + 4x2 – 9x – 36 has 4 terms. use factoring by grouping to find the correct factorization.

x3 + 4x2 – 9x – 36

= x^2( x + 4) - 9(x + 4)

= (x + 4)(x^2 - 9)

= (x + 4)(x - 3)(x + 3)

24/56=hx^7

step-by-step explanation:

x^3 + 4x^2 – 9x – 36

Factor out common terms in the first two terms and the last two terms

x^2 (x + 4) - 9 (x + 4)

factor out the common term (x + 4)

(x + 4) (x^2 - 9)

Rewrite

(x + 4) ( x^2 - 3^2)

Use the difference of squares

(x + 4) (x + 3) (x - 3)

Hope this helps 🙂

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
