Given √3 + √5 To prove: √3 + √5 is an irrational number. Let us assume that√3 + √5 is a rational number. So it can be written in the form a/b √3 + √5 = a/b Here a and b are coprime numbers and b ≠ 0 Solving √3 + √5 = a/b On squaring both sides we get, (√3 + √5)² = (a/b)² √3² + √5² + 2(√5)(√3) = a²/b² 3 + 5 + 2√15 = a²/b² 8 + 2√15 = a²/b² 2√15 = a²/b² – 8 √15 = (a²- 8b²)/2b a, b are integers then (a²-8b²)/2b is a rational number. Then √15 is also a rational number. But this contradicts the fact that √15 is an irrational number. Our assumption is incorrect √3 + √5 is an irrational number. Hence, proved.

3x²+5x+2 3x²+3x+2x+2 3x(x+1) +2(x+1) (X+1)(3x+2) X+1is equal to 0 Then x is equal to -1 Here we can say that alpha is equal to -1 Similarly, If we take 3x +2 Beta is equal to x is eqal to -2/3 1/alpha+ 1/beta 1/-1 +1/-2/3 Is eqal to -5/3
