Question

if alpha and beta are the zeros of polynomial 12 x square + 2 x - 4 find the value of alpha - beta​

Answer 1

Answer:

alpha= -1/2 and beta=-2/3

Step-by-step explanation:

In this equation

12x+2x-4=0

2 is common so cut the 2 from this equation so the equation will be

6x+x-2=0

Now multiply A and B = 6×2=12

so, 6x2+4x-3x-2=0

2x(3x+2)1 (3x+2)=0

(2x+1) (3x+2) =0

2x+1=0 , 3x+2=0

x= -1/2 , x= -2/3

alpha= -1/2, beta = -2/3
