Question

find the zeros of quadratic polynomial 2x square - 3 + 5 x and verify the relationship between zero and coefficient​

Answer 1

Answer:

Step-by-step explanation:

2x²+5x-3=0

2x²+6x-x-3

2x(x+3)-1(x+3)

(2x-1)(x+3)

α=1/2 and β=-3

Verification

α+β=-b/a

1/2-3=-5/2(LHS=RHS)

αβ=c/a

1/2×-3=-3/2(LHS=RHS)

Verified.

Answer 2

Step-by-step explanation:

2x^2 + 5x - 3

2x^2 + x( 6-1 ) - 3

2x^2 + 6x - x - 3

2x ( x + 3 ) -1 ( x + 3 )

( x + 3 ) ( 2x - 1 )

x = (-3) , 1/2

alpha = (-b)/a = -5/2

beta = c/a = -3/2
