The polynomial x3 + 4x2 β 9x β 36 has 4 terms. Use factoring by grouping to find the correct factorization.
Question
Answer:
x^3 + 4x^2 β 9x β 36Factor 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)Β
Use the difference of squares
(x + 4) (x + 3) (x - 3)
Hope this helps :)
