Answer:
1. P(x) = x^3 +4x^2 -27x -90
2. degree: 3; constant: -90
Step-by-step explanation:
1. You can multiply the factors 2 at a time using the distributive property.
P(x) = (x +6)(x(x -5) +3(x -5)) = (x +6)(x^2 -5x +3x -15)
= (x +6)(x^2 -2x -15) = x(x^2 -2x -15) +6(x^2 -2x -15)
= x^3 -2x^2 -15x +6x^2 -12x -90
P(x) = x^3 +4x^2 -27x -90

2. The degree is 3, the highest power. The constant term is the one without any variables: -90.
