What is the factored form of this polynomial? x2 + 5x − 36
A. (x + 4)(x + 9)
B. (x − 4)(x + 9)
C. (x − 5)(x + 8)
D. (x − 4)(x − 9)

Step-by-step explanation:

hello :

B. (x − 4)(x + 9)

calculate : (x − 4)(x + 9)= x²+9x-4x-36 = x²+5x-36

B is correct

Step-by-step explanation:

We need two numbers that add up to +5, and when multiplied get -36. B is the only one that gives a product of -36 and a sum of +5 (-4*9 and -4+9 respectively)
