Find the zeros of the quadratic polynomial 4√5x^2-24x-9√5 and verify its relationship between its zeroes and required urgently for my assignment

The zeros of the quadratic polynomial are

 and

The relationship between its zeroes and coefficients in the procedure

Step-by-step explanation:

step 1

Find the zeros

we know that

The formula to solve a quadratic equation of the form is equal to

in this problem we have

so

substitute in the formula

step 2

Find the sum of the zeros and the product of the zeros

Sum of the zeros

Product of the zeros

step 3

Verify that

Sum of the zeros= -Coefficient x/Coefficient x²

Coefficient x=-24

Coefficient x²=4√5

substitute

therefore

the relationship is verified

step 4

Verify that

Product of the zeros= Constant term/Coefficient x²

Constant term=-9√5

Coefficient x²=4√5

substitute

therefore

the relationship is verified

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
