Question

find the coefficient x^2 and x in the product of (x-3) (x+7) (x-4).

Answer 1

Answer:

coefficient x^2=0

coefficient x= -37

Step-by-step explanation:

(x-3) (x+7) (x-4)

{(x-3) (x+7)} (x-4)

{x(x-3)+7 (x-3)} (x-4)

{x²-3x+7x-21}(x-4)

{x²+4x-21}(x-4)

x(x²+4x-21)-4(x²+4x-21)

x³+4x²-21x-4x²-16x+84

x³-37x+84

coefficient x^2=0

coefficient x= -37
