Question

Usine algebraic identity, find the coefficients of x^2, x and constant term without actual expansion
(x+5)(x+6)(x + 7) ​

Answer 1

Answer:

coefficient of x2 will be 18

and coefficient of x will be 72

Step-by-step explanation:

(x+5)(x+6)(x+7)

x2 + 6x + 5x + 30(x+7)

x3 + 7x2 + 6x2 + 42x + 30x + 5x2 + 210

x3 + 18x2 + 72x
