 \sf {x}^{2}  + (a + 1)x + b \\

शून्यक = 2 और -3

हम जानते है,

  • शून्यकों का योग = -b/a
  • शून्यकों का गुणनफल = c/a

 =  > 2 + ( -  3) =  \frac{ - (a + 1)}{1}  \\  \\  =  >  \:  \:  \:  - 1 =  - ( a+ 1) \\  \\  =  >  \:  \:  \: a + 1 = 1 \\  \\  =  >  \:  \:  \:  \:  \: a = 0

तथा,

 =  > 2 \times ( - 3) =  \frac{b}{1}  \\  \\  =  > \:  \:  \:  \:  \:  b =  - 6

अतः

● विकल्प 4 सही उत्तर है।
