Question

Find the constant term for each of the following:

P(x)=(x-2)(x-3)(x+7)
P(x)=(x+2)(x-3)(x+7)
P(x)=.5(x-2)(x-3)(x+7)
P(x)=5(x-2)(x-3)(x+7)
P(x)=-5(x-2)(x-3)(x+7)

Answer 1

Answer:P (x) = ( x + 2 ) ( x - 3 ) ( x + 7 )

(x^2 - 3x + 2x - 6) ( x + 7 )

( x^2 - x - 6 ) ( x + 7 )

( x^3 + 7x^2 - x^2 - 7x - 6x - 42 )

(x^3 + 6x^2 - 13x - 42)

The constant term in this function is - 42
