What form is the equation 12y=2x=24

lukranit [14]

Answer:

Step-by-step explanation:

Simplifying

12y + 2x = 24

Reorder the terms:

2x + 12y = 24

Solving

2x + 12y = 24

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12y' to each side of the equation.

2x + 12y + -12y = 24 + -12y

Combine like terms: 12y + -12y = 0

2x + 0 = 24 + -12y

2x = 24 + -12y

Divide each side by '2'.

x = 12 + -6y

Simplifying

x = 12 + -6y

Describe how you can determine the number of solutions when a quadratic equation is written in perfect square form.

pochemuha

A quadratic is an expression of the form ax²+bx+c.

If the quadratic is in the perfect square form, it could be factored to look something like this:

(x+a)² or (x-a)²

Both of the above forms have one solution, that is "-a" and "a" respectively.

So if your quadratic equation is of the form:

(x±a)² = b, where b > 0
You can solve for "x" by taking the square root of both sides and getting 2 solutions -- ±a±√b.

And if your quadratic equation is of the form:
(x±a)² = b, where b < 0
Then when you try taking the square root of both sides, you will have to take the square root of a negative number, which means you will not get a real solution. Therefore, there will be zero solutions.

And finally if your quadratic equation is of the form:
(x±a)² = b, where b = 0
Then you will have one solution -- ±a.

Hope that helps!
