 *3.1 Многочлен*
 Многочленом (полиномом) $P_n (x)$ степени n $gt.eq$ 1 будем называть функцию вида:
 #set align(center)
-$P_n (x) = a_0 + a_1 x + a_2 x_2 + dots + a_n x_n,i in RR, a_n eq.not 0, i in {1, 2, dots, n}$
+$P_n (x) = a_0 + a_1 x + a_2 x^2 + dots + a_n x^n,i in RR, a_n eq.not 0, i in {1, 2, dots, n}$
 
 #set align(left)
 Многочленом нулевой степени назовем произвольную константу, отличную от нуля. У тождественно равного нулю многочлена степенью будем называть символ $-infinity$.
