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)
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.
