Question

3) If a and ß are the roots of the quadratic equation 2x2 + 6x -5 = 0, then find (a + B) and
αχ β.​

Answer 1

Answer:

∝+β=  -3  

∝β=  -5/2 or -2.5

Step-by-step explanation:

compare the given equation with the general form : ax²+bx+c=0

∴a= 2, b=6, c= -5

as,

    ∝+β= -b/a

          = -(6)/2

          = -3

and as,

   ∝β= c/a

        =  -5/2

        =  -2.5
