Step-by-step explanation:

u will have to then again add eq 3 abd 4 and get ans

Answer 2

10).

GIVEN ; ALPHA AND BETA ARE ZEROES OF POLYNOMIAL;

X^2 - 2 X - 8

BY FACTORISING POLYNOMIAL,WE GET ;

=>. X ^2. -4 X + 2 X - 8

=>. X ( X -. 4 ) + 2 ( X - 4)

=>. ( X + 2 ) ( X - 4)

SO ,THE ZEROES OF POLYNOMIAL ARE X = -2 ,X = +4

THEN , 2 ALPHA = 2 × -2 = -4 , 2 × BETA = 2 × 4 = 8

AS KNOW REQUIRED POLYNOMIAL ;

=> K { X^2 - ( 2 ALPHA + 2 BETA ) X + (PRODUCT OF ZEROES ) }

=> K { X^2 - ( -4 + 8 )X + (-4)(8) }

=>. K ( X^2 +4X - 32 )

2). 99X +. 101 Y = 499 (1)

101 X + 99 Y = 501 (1)

THEN, BY USING METHOD OF ELIMINATION ;

BY OPERATING 101 × (1) - 99 × (2) ,WE GET ;

=>. 101 ( 99 X + 101 Y = 499) - 99(101X + 99Y = 501)

=> 9999 X + 10201 Y =. 50399

- 9999 X + 9801 Y= 49599

400 Y. =. 800

THEN ,Y = 2

NOW, 99X. +. 101 Y = 499

99X + 101(2). = 499

99X + 202 = 499

99X = 499 - 202

99X = 297

X = 297 /99 = 3
