Explicación paso a paso:
a.- Q(×) = -x⁵ + 2x³ -x² x = 1
Q(x) = -(1)⁵ + 2•1³ -(1)²
Q(x) = -1 + 2•1 -1
Q(x) = -1 + 2 -1
Q(x) = 0
b.- P(x,y) = - x⁴y - x²y + 7xy - 2 x = 1 y = 2
P(x,y) = - (1)⁴•2 - (1)² • 2 + 7 • 1 • 2 - 2
P(x,y) = - 1 • 2 - 1 • 2 + 14 - 2
P(x,y) = - 2 - 2 + 14 - 2
P(x,y) = - 6 + 14
P(x,y) = 8
