Question

Find the coefficient of x²and x from the product of (x-3)(x+7)(x-4)​

Answer 1

Answer:  x=-37,    x²=0

Step-by-step explanation:

consider (x-3)(x+7)

we get x^2 +4x -21

then again (x^2+4x-21)(x-4)

we get x^3-4x^2 +4x^2 -16x -21x+84

x^3-37x +84

coefficient of x^2 is 0

coefficient of x is -37
