प्रश्नावली 2.3

Q1. x³ + 3x² + 3x + 1 को निम्नलिखित से भाग देने पर शेषफल ज्ञात कीजिए : 

(i) x + 1 

(ii) x - ½ 

(iii) x 

(iv) x + θ

(v) 5 + 2x 

हल : (i) x³ + 3x² + 3x + 1 को x + 1 से भाग देने पर 

अत: भाग देने पर शेषफल 0 है | Ans.

हल : (iii)  x³ + 3x² + 3x + 1 को x से भाग देने पर       

अत: भाग देने पर शेषफल 1 है | Ans.

हल : (iv) x³ + 3x² + 3x + 1 को x + π से भाग देने पर 

अत: भाग देने पर शेषफल - π³ + 3π² - 3π + 1 है | Ans.

हल : (v) x³ + 3x² + 3x + 1 को 5 + 2x से भाग देने पर    

Q2. x³ - ax² + 6x - a  को x - a से भाग देने पर शेषफल ज्ञात कीजिए |

हल : p(x) = x³ - ax² + 6x - a  और g(x) = x - a है | 

g(x) = x - a का शुन्यक

अत:  x - a = 0

     x = a

अत: शेषफल प्रमेय से

p(x) को x - a से भाग देने पर शेषफल प्रमेय द्वारा शेषफल p(a) प्राप्त होगा |

इसलिए, p(a) = (a)³ - a(a)² + 6(a) - a  

            = a³ - a³ + 6a - a

                           = 5a

अत: शेषफल 5a है |
