Let -3= be (ã+ß) & 2=(ã+ß) by Quadratic formula....→ x²-(ã+ß)x+àß=0 x²-(-3)x+2=0 [x²+3x+2=0]..... 👍👍👍

:》Sum of zeros = -3 ; Product of zeros = 2 :》Quadratic polynomial = k[x2 - ( Sum of zeros)x + ( Product of zeros)] :》k [ x2 - (-3)x + 2] :》k [ x2 + 3x + 2] ,where k =1 :》 Quadratic Polynomial = x2 + 3x +2

The answer is Let 3+2√2 be a rational number and it can be written in the form of : p/q = 3+2√2 p/q -3 = 2√2 p-3q / q =2√2 Rational = irrational Therefore our assumption was wrong. Hence 3+2√2, is an irrational number.

S7 = 7/2{2a+(n-1)d} => 49= 7/2{2a+(n-1)d} => 14= 2a + (7-1)d =>14 = 2a +6d => a + 3d = 7 ---------------(dividing by 2) => a = 7-3d -----------------(i) for S17:- S17 = 17/2 {2a+(n-1)d} => 289= 17/2 {2a+(17-1)d} => 34 = 2a + 16d => a = 17- 8d ---------------(ii) by eq(i) and eq(ii):- 17 - 8d = 7-3d =>10=5d =>d=2 again by eq(i):- a =1 by Sn:- Sn = n/2 {2a+(n-1)d} =>Sn = n/2{2+(n-1)2} => Sn = n + n^2 - n => Sn = n^2

d is the common difference and a is the first term this series forms A.P. as it has common difference and a2-a1 = a3-a2=3 d =a2-a1 = 3 a =2 and given Sn = 155 also Sn =n/2 {2a+(n-1)d} => 155 = n/2{ 4 + (n-1)3} => 310= 4n +3n^2 - 3n => 3n^2 +n -310 =0 => 3n^2 -30n +31n -310 =0 =>3n(n-10)+31(n-10)=0 =>(3n+31)(n-10)=0 since number of terms (n) cant be negative so n=10
