If the domain of the function f(x)= log_(10 x^2-17 x+7)(18 x^2-11 x+1) is (-∞, a) ∪(b, c) ∪(d, ∞)-{e}, then 90(a+b+c+d+e) equals:
If the domain of the function
$$f(x)=\log _{\left(10 x^2-17 x+7\right)}\left(18 x^2-11 x+1\right)
$$
is $\displaystyle (-\infty, a) \cup(b, c) \cup(d, \infty)-\{e\}$, then
$$90(a+b+c+d+e) \text { equals: }
$$
