Question

If a and B are roots of the equation x2 +
px + 20 = 0 and a - B = 1 then ●P= +4
●P= +5
●P= +9
●P= +7​

Answer 1

Answer:

Solution:-

given by quadratic equation:-

2 {m}^{2} - 5m = 0 \\ m(2m - 5) = 0 \\ m = 0 \\ m = \frac{5}{2}

●here , m =( 0 , 5/2)

●the given values of m = 2 , does not exits

●x = 5/2 is the root of given equation (2m²-5m=0) . ans
