Question

Find the coffient of x² and x in the product of (x-5) (x+3) (x+7)​

Answer 1

Answer:

Coefficient of

$x ^{2} = 5$

and coefficient of X= -29

Answer 2

Answer:

The coefficient of x² = 2 and x = 0

Step-by-step explanation:

(x-5) (x+3) (x+7)​

∴ x(x+3) -5(x+3) +x(x+7)​ -5(x+7)​

∴ x² + 3x -5x -15 +x² +7x -5x -35

∴ x² +x² + 3x -5x +7x -5x -15 -35

∴ 2x² -2x +2x -50

∴ 2x² -50

∴ The coefficient of x² = 2 and x = 0
