Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 5 = 4x

Thus, the two root of the given quadratic equation    is 5 and -1 .

Step-by-step explanation:

Consider, the given Quadratic equation,

This can be written as ,  

We have to solve using quadratic formula,

For a given quadratic equation we can find roots using,

 ...........(1)

Where,   is the discriminant.

Here, a = 1 , b = -4 , c = -5

Substitute in (1) , we get,

and

and

and

Thus, the two root of the given quadratic equation is 5 and -1 .

4 + 5 7/9= 9 7/9

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
