Answer:
(x+9) is one of the factor
Step-by-step explanation:
x^2 + 5x - 36
factor the given expression
Product is -36 and sum is +5
We find out two factors whose product is -36 and sum is +5
9 times -4 = -46
9 - 4= 5
x^2 +9x -4x -36
Group first two terms and last two terms and factor out GCF
(x^2 +9x)+(-4x -36)
x(x+9) - 4(x+9)
(x+9)(x-4)
So (x+9) is one of the factor
