Question

tick the correct one a quadratic polynomial whose sum of zeros and product of zeros are - 4 and - 5 respectively option
a x square + 4 x minus 5 option
b.x square - 4 x minus 5 option
c .x square - 9 x - 20 option
d . x square + 9 x + 20​

Answer 1

let's , quadratic equation : ax2 + bx + c

sum of zeros = -b/a

-4 = -b/a

product of zeros = c/a

-5 = c/a

so , a = 1 , b = 4 , c = 5

equation ; ax2 + 4x -5

so , option a is correct

thank u ❤️

Answer 2

Answer:

Let's quadratic equation = ax2+bx + C

sum of zeros = -b/a

-4 = -b/a

product of zeros = c/a

-5 =c/a

so, a= 1 ,b=4 ,c=5

equation : ax2+ 4x -5
