URGENT PLEASE Solve the equation using the quadratic formula. 3x^2 - 18 = -6

x = 2 and x = -2

Step-by-step explanation:

The quadratic formula of a quadratic of the form ax² + bx + c is:

x = or x =

Here, our equation is: 3x² - 18 = -6. Let's move all the terms to one side:

3x² - 12 = 0

a = 3 and c = -12. Notice that since there's no x term, b = 0.

Plug these into the quadratic formula:

x =  

or

x =

So, x = 2 and x = -2.

x = -2, x = 2

Step-by-step explanation:

The quadratic formula:

You can find the variables a, b, and c in the standard form of a quadratic equation:

Your equation:

The variables are:

a = 3

b = 0

c = -12

Substitute those for the variables in the quadratic formula:

You can simplify this to get:

(or positive square root of 144.)

The square root of 144 is 12, and 12/6 = 2.

The x-values are -2 and 2.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
