find the quadratic polynomial, the sum and product of whose zeros are root 2 and -12 respectively.

Answer» let ,alpha and bita are zeroesso,alpha+bita= 2 and alpha•bita=-12f(x)= xsquare-(alpha+bita)x+alpha•bita =x² -2x+(-12) =x²-2x-12 required polynomial= x²-2x-12
Kya Aaisha tumhe itna bhi nahi aata.Ans. Braket me X ka square phir _ braket me sum of zeroes braket close phir × X phir + product of zeroes braket close
