Question

find the sum of and product of zeros of the quadratic polynomial 3 x square - 4 x + 7

Answer 1

Here your answer goes

Step :- 1

Given Polynomial ,

$3x^2 - 4x + 7$

$3x^2 + 7x - 3x + 7$

$x ( 3x + 7 ) 1 ( 3x + 7 )$

$(3x + 7 ) ( x + 1 )$

x = 7/3 , -1

Step :- 2

Sum of the zeros = -b/a

7/3 + (-1) = -3/3

Step :- 3

Product of the zeros = c/a

7/3 * (-1) = -7/3

Answer 2

compare it with ax2 +bx +c
sum =-b/a =-(-4)/3 =4/3
product =c/a =7/4
