Answer:
p = 3
q = -6
Step-by-step explanation:
Work backwards from the roots:
x = 
3x = 2
3x - 2 = 0
Other root:
x = -3
x + 3 = 0
Multiply them together:
(3x - 2)(x + 3) = 0
3x² - 9x + 2x - 6 = 0
3x² - 7x - 6 = 0
p = 3
q = -6

Answer:
Step-by-step explanation:
There are no factors outside the parentheses that need to be distributed, so the parentheses can be simply dropped:
6 -2x +15 -3x
The terms can be rearranged to put like terms next to each other:
-2x -3x +6 +15
and the like terms can be combined.
-5x +21 . . . . simplified expression
__
Put the value of x where x is, then do the arithmetic.
-5(-0.2) +21 = 1 +21 = 22
