Verified answer

Answer:

21/4

Step-by-step explanation:

a= 2

b= -7

c= 3

So the equation is,

ax^2 +bx +c = 0

or, 2x^2 - 7x +3 = 0 [ by putting the values of a,b and c]

or, 2x^2 - 6x -x + 3 = 0

or, 2x (x-3) - 1 ( x - 3 ) =0

or, (2x-1)(x-3) = 0

So,

x= 1/2 or x = 3

so Alpha = 1 / 2 and Beta = 3

alpha beta square + alpha Square beta

= 1/2*9+1/4*3

=9/2+3/4

=21/4

So The Answer Is 21/4
