Answer 1

Step-by-step explanation:

Factors of 1st and 2nd Term Coefficient Multi.

2,2,2,3,3

8×9

8+9

Both give 72/17!

x²+8x+9x+72

x(x+8) +9 (x+8)

Thus, Answer = (x+9)(x+8)

Answer 2

x^2 + 17x + 72

x^2 + 9x + 8x + 72

x( x + 9) + 8x( x + 9)

( x + 9) + (x + 8)

x + 9 = 0 or x + 8 = 0

x = -9 or x = -8
