Use the quadratic formula to solve the equation 2x^2+2x-4=0
const2013 [10]

Answer:

<h2>x = -2 or x = 1</h2>

Step-by-step explanation:

The quadratic formula for the quadratic equation ax² + bx + c = 0:

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

2x^2+2x-4=0\qquad\text{divide both sides by 2}\\\\x^2+x-2=0

a=1,\ b=1,\ c=-2

Substitute:

x=\dfrac{-1\pm\sqrt{1^2-4(1)(-2)}}{2(1)}=\dfrac{-1\pm\sqrt{9}}{2}=\dfrac{-1\pm3}{2}\\\\x_1=\dfrac{-1-3}{2}=\dfrac{-4}{2}=-2\\\\x_2=\dfrac{-1+3}{2}=\dfrac{2}{2}=1

Valentina's family is planning to have a party for her quinceanera. They are considering two different locations to rent for her
CaHeK987 [17]

Answer:

number of hours = 3 hours

Step-by-step explanation:

Let

x = number of hours

Casa Lucia = 200 + 500x

Silver Fox = 1,100 + 200x

To solve the equation, equate both cost of rent

Casa Lucia = Silver Fox

200 + 500x = 1,100 + 200x

200 - 1,100 = 200x - 500x

-900 = - 300x

x = -900 / -300

x = 3 hours

number of hours = 3 hours

The solution to the system of equations in this real-world context represents the number of hours both locations can be rented with the same cost.

It means both locations cost the same if rented for 3 hours each
