Someone please help me out!! I’m struggling

This is called "completing the square"

It is a technique to  solve a quadratic equation. It involves "moving all

of the constants to the right" , then doing a "move" on the left hand side. This move "creates a perfect square".. This is done by taking 1/f of the "B" term and squaring it... this will "un-balance" the  sides of the equation... to balance it out you have to "add" some stuff to the right hand side... when done the left side will be "a perfect square" .. last step will be take the square root of both sides.

Step-by-step explanation:

±

= ±

x = -6 ±

Step 1: -15

Step 2: b = 12, c = 36

Step 3-4: x² + 12x + 36 = -15 + 36, which simples to (x + 6)² = 21

If there is a step that has you solve for x, it should be -6 + √21 or -6 - √21.

Step-by-step explanation:

Step 1 is pretty simple. All we have to do is subtract 15 from 0 to get the first blank.

x² + 12x = 0 - 15

x² + 12x = -15

Step 2:

b is the coefficient on x, which is 12.

Then, use the formula mentioned:

As a result of that, c is 36.

Now to substitute and simplify. (Steps 3-4)

x² + 12x + 36 = -15 + 36

To factor an equation, think about it like this: Find two numbers that add to the coefficient of x, and multiply to the constant. So what two numbers add to 12, and multiply to 36? That would be 6 & 6 (6 + 6 = 12; 6 × 6 = 36).

(x + 6)² = -15 + 36

Add 36 to -15 to get 21.

(x + 6)² = 21

That should solve steps 1-4, but I will go on ahead and give the final answer to the entire problem.

(x + 6)² = 21

Yes, you are about see what I just factored be expanded back over again. It's part of the process.

x² + 12x + 36 = 21

Now subtract 21 from both sides.

x² + 12x + 36 - 21 = 21 - 21

x² + 12x + 15 = 0

Now onto the hard part of this: the quadratic formula. a = (the understood) 1, b = 12, and c = 15.

x = (-b ± √b² - 4ac)/2a

x = -12 ± √12² - 4(15)/2

x = -12 ± √144 - 60/2

x = -12 ± ✓84/2

x = -6 + √21 or -6 - √21

idk the answer but just put a

step-by-step explanation:

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
