maka nilai p dan q adalah

f(x) = px^ + qx

f(2) = p(2)^ + q(2)
f(-2) = p(4) +2q
f(-2) = 4p + 2q

f(-2) = p(-2)^ + q(-2)
f(10) = p(4) + q(-2)
f(10) = 4p + (-2q)
f(10) = 4p - 2q

-2 = 4p + 2q
10 = 4p -2q
___________ _
-12 = 4q
-3 = q

-2 = 4p + 2(-3)
-2 = 4p + (-6)
-2 = 4p - 6
-2 + 6 = 4p
4 = 4p
1 = p

jawaban nya = a. p = 1 dan q = -3
