y = [x^4 - 29x^2 + 100] / [x^2 - 3x - 10]
__x^4 - 29x^2 + 100 = 0 x^2=t => t1=25, t2=4 =>
x^4 - 29x^2 + 100 = (x^2 - 25)(x^2 - 4)
__x^2 - 3x - 10 = 0 x1=5, x2= -2 =>
x^2 - 3x - 10 = (x-5)(x+2)
=>
y = (x^2 - 25)(x^2 - 4) / (x-5)(x+2) =
= (x+5)(x-5)(x+2)(x-2) / (x-5)(x+2) =
= (x+5)(x-2) =>
y = x^2 + 5x - 2x - 10 = x^2 + 3x - 10
Построй график y = x^2 + 3x - 10
Дальше легко.
удачи!
