Step 1: Simplify both sides of the equation.
n+2=−4−n
n+2=−4+−n
n+2=−n−4
Step 2: Add n to both sides.
n+2+n=−n−4+n
2n+2=−4
Step 3: Subtract 2 from both sides.
2n+2−2=−4−2
2n=−6
Step 4: Divide both sides by 2.
2n -6
--- = ---
2 2
n=−3

D . what is the number sentence?
Answer:
The roots are -2 and -3
Step-by-step explanation:
In the function x² + bx + c, <em>a</em> is equal to 1, then the factored form of this function is: (x - x1)*(x - x2) where x1 and x2 are the roots.
Wilma got the following expression:
(x - 1)*(x - 6) = x² - 6x - x + 6 = x² - 7x + 6, where '+6' is correct but '-7x' is incorrect.
Greg got the following expression:
(x + 1)*(x + 4) = x² + 4x + x + 4 = x² + 5x + 4, where '+5x' is correct but '+4' is incorrect.
Therefore the quadratic equation is: x² + 5x + 6. Its roots are:
