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
Minus 16x both sides and add 28 to both sides
x^2-16x+28=0
factor
hmm, what 2 numbers multiply to 28 and add to -16
hmm
1 and 28? nope
2 and 14? yep
since middle term is negative and last tem is positive, both of the factors are negative
(x-14)(x-2)=0
set each to zero
x-14=0
x=14
x-2=0
x=2
x=2 and 14
