∴ q? = 3q - 10,q^4=sup2 - 10q
Let h (x) = bx&; Sup2+cx+d (b, c, d are rational numbers, b≠0)
h(a)= b(q^4+q&; sup 2+4+2q & amp; sup 3-4q & amp; sup 2-4q)/4+c(q & amp; sup2+q-2)/2 + d = q
Introduce simplification to get CQ &;; sup 2/2+(c/2-2 b- 1)q+(d-c-4b)= 0
Q is irrational, and b, c, d C and d are rational.
∴c = 0,c/2 - 2b - 1 = 0,d-c-4b = 0
Get d = -2.
∴h(0) = d = -2
