Question

5. If the α and β are the zeros of 2x²+5x-9, then the value ofα. Β is *

Answer 1

Answer:

-9/2 or -4.5

Step-by-step explanation:

If α and β are zeroes (or solutions) of the quadratic equation of the form : ax^2+bx+c

then,

α+β= - (b/a)

and

α•β= c/a

Here a=2,b=5 and c= -9

hence value of α•β is = c/a =-9/2= -4.5
