00:00 - 00:59 | hello everyone is using factor theorem is the following y cube minus 2 y square - 29 Y - 42 let's move towards the solution of this sum let p y equal to P Y is equal to y cube minus 2 y square - 29 Y - 42 now by putting Y is equal to 1 we get bigot one which is equal to 1 cube minus 2 into 1 - 29 into 1 - 42 which is equal to 1 - 2 - 29 - 42 |

01:00 - 01:59 | which means 1 - 73 which is equal to minus 72 therefore not equal to zero now by putting Y equal to minus 2 Y is equal to minus to forget your of minus 2 is equal to minus 2 minus 2 into - 2 - 29 into - 2 - 42 which is equal to minus 8 - 8 42 which is equal to zero therefore of minus 2 is equal to zero Y + 2 |

02:00 - 02:59 | is a factor of is a factor of now by long division by using long division will find the other factors of this expression now my doing long Division with Y + 2 Y + 2 is a factor of y y + 2 x cube minus 2 y square - 29 Y - 42 B Y + 2 possibility curve y square x square Y + 2 we get y cube + 2 y square after changing Sin B is minus y cube and |

03:00 - 03:59 | the remaining terms are now minus 4 y square - 29 Y - 42 now we will take - 4 x minus 4 Y + 2 we get minus 4 y square - 8 now we will change sin minus 4 y square is cancelled with + 4 y square and the remaining term for now -21 Y - 42 now we will take - 21 week 8 - 21 - 42 after changing time -21 sensor with + 21 by and - it was cancelled with plus 42 and the remainder is now by division algorithm dividend which is by 2 minus 2 y square - 29 Y - |

04:00 - 04:59 | 42 is equal to divisor which is Y + 2 X question which is why I squared minus 4 Y - 21 now we will do middle term splitting we get y square - 7 x + 3 Y - 21 mins + 2 after regrouping the get y square - 7 x + Y - 21 is equal to Y + 2 after taking why is there common factor and here as their common actor secret now Y + 2 Y + 3 and Y minus y cube minus 2 y square - |

05:00 - 05:59 | 29 Y - 42 is equal to Y + 2 X + 3 x minus 7 which is the fittest form of the given expression thank you |
