What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?

RideAnS [48]

Step-by-step explanation:

The function is as follows :

$f(x) = x^2 + 5x + 5$

We need to find the zeroes of the function in the simplest radical form.The zero of the above function is given by :

$x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}$

Here,

b = 5

a = 1

c = 5

So,

$x=\dfrac{-5\pm \sqrt{5^2-4\times 1\times 5} }{2(1)}\\\\x=\dfrac{-5\pm \sqrt{25-20} }{2(1)}\\\\x=\dfrac{-5\pm \sqrt{5} }{2}$

Hence, the correct option is (c).

1. How do you define quadratic equations?

oksian1 [2.3K]

Answer:

$ax^{2} +bx+c^{2}=0$

Step-by-step explanation:

A quadratic equation is a equation that takes the form: $ax^{2} +bx+c^{2} = 0$

Ex. Using our definition of quadratic equations, $ax^{2} +bx+c^{2}=0$ ,

We can set a = 2, b = 1, c = 6:

$2x^{2} +x+6^{2}=0$

$2x^{2} +x+36=0$

Which can then be solved (if you are trying to solve it) as:

$(2x+9)(x-8)=0$

$x=\frac{9}{2}, 8$

Lucy earns 52 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells.

Misha Larkins [42]

Answer:

A = B + 52

Step-by-step explanation:

A is the total amount each week. 52 is the initial amount that she earns each week. Then, B represents the amount of books she sells. So, 15 books can be represented by

A = 15 + 52 = 67
