Answer:

-2 or 9

Step-by-step explanation:

x² - 7x - 18

-9 and 2

x² - 9x + 2x - 18

x( x - 9) + 2(x - 9)

(x + 2) (x - 9)

x = -2 or x = 9

If D = Z + 6 and C = -2 + Z - Z^2, find an expression that equals 3D + C in standard form

kykrilka [37]

Answer:

4Z+16-Z²

Step-by-step explanation:

Given that,

D = Z+6

C = -2 + Z - Z²

We need to find the value of 3D+C.

So,

3D+C = 3(Z + 6)+(-2 + Z - Z²)

= 3Z+18-2+Z-Z²

= 4Z+16-Z²

So, the required expression is 4Z+16-Z².
