Example Question:

X²+6x-14=0

Quadratic equations are usually in the form Ax²+Bx=C. Completing the Square is a technique for rewriting this equation in the form (x+a²)+b.

The example I provided is in standard form.

Here's what I did:

Step 1: Move the "C" to the other side (in this case it's negative 14, so you add 14 to both sides of the equation to move it).

Step 2: Leave a blank after Ax²+Bx. In this case, it'll look like: X²+6x+_____= 14.

Step 3: Use the box to find the missing "C". Idk if you can see the photo after the 1st one, but I circled the spaces in green. Those spaces indicate 2 factors that add up for B (in this case, 6). Those same factors will eventually multiply each other to get 9.

Step 4: Give the new "C" to both sides of the equation. What this means is that after you multiply the factors on the outside of the box, you put the number on both sides. The 3rd picture I drew is the process of finding the outer factors (by plugging in 3x to the spaces that were circled).

If you can't see it, it's (X+3)•(X+3).

The 4th picture is me plugging the new "C" (9) to both sides of the equation. 3 times 3 is 9. You multiply the 3's on the outside to get the factors on the inside.

Step 5: Use Step 3 box to write (perfect square)² of left hand side.

What this means is that you take the factors on the outside and rewrite it in perfect square form. like shown in picture 5. If you can't see it, it's like this:

(X+3)•(X+3) turns to (X+3)²=23.

The 23 was from adding 14+9 together.

So the final Answer would be:

(X+3)²=23.

Which is the length of the hypotenuse of the triangle?​
Pepsi [2]

Since this is a right triangle, we can use the Pythagorean Theorem, which states a² + b² = c² in a right triangle.

Plugging our numbers in, we get:

(12)² + (35)² = c²

From there, we can square the numbers.

(144) + (1225) = c²

Then, we can add them together to find the sum;

(1369) = c²

And finally, we can find the square root of both sides.

(37) = c

Therefore, 37 is the answer and your answer choice is correct.

Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?
exis [7]

The solution set of the equation is all reals ⇒ 3rd answer

Step-by-step explanation:

The solution set of an function is the set of all vales make the equation true. The equation has:

  • Solution if the left hand side is equal to the right hand side
  • No solution if the left hand side doesn't equal the right hand side

∵ The equation is 18 - 3n + 2 = n + 20 - 4n

- Add the like terms in each side

∴ (18 + 2) - 3n = (n - 4n) + 20

∴ 20 - 3n = -3n + 20

- Add 3n to both sides

∴ 20 = 20

In the equation of one variable, when we solve it if the variable is disappeared from the two sides, and the two sides of the equations are equal, then the variable can be any real numbers, if the two sides are not equal, then the variable couldn't be any value

∵ The the variable n is disappeared

∵ The left hand side = the right hand side

∴ n can be any real number

∴ The solution set of the equation is all real numbers

The solution set of the equation is all reals

icang [17]
Volume formula of a sphere:
\frac{4}{3}\pir³

given:
r = 3 

V = \frac{4}{3}\pi(3)³
V = \frac{4}{3} × 27\pi
V = 36\pi units³ (in terms of \pi)
V = 113.097 units³ ≈ 113.1 units³
