Question
What is the factorization of the polynomial below?x2 - 5x - 36A.(x - 9)(x + 4)B.(x - 9)(x - 4)C.(x + 9)(x - 4)D.(x + 9)(x + 4)SUBMITarrow_backPREVIOUS
Solution
The factorization of the polynomial x^2 - 5x - 36 is done by finding two numbers that multiply to -36 (the constant term) and add to -5 (the coefficient of the middle term).
The two numbers that satisfy these conditions are -9 and +4.
Therefore, the factorization of the polynomial x^2 - 5x - 36 is (x - 9)(x + 4).
So, the correct answer is A. (x - 9)(x + 4).
