Solve the following quadratic by<br> completing the square.<br> y = x^2 - 6x+7

kozerog [31]

Answer:

$x= 3+\sqrt{2}, \quad x= 3 -\sqrt{2}$

Step-by-step explanation:

<u>Given quadratic equation</u>:

$y = x^2 - 6x+7$

To complete the square, begin by adding and subtracting the square of half the coefficient of the term in x:

$\implies y = x^2 - 6x+\left(\dfrac{-6}{2}\right)^2-\left(\dfrac{-6}{2}\right)^2+7$

$\implies y = x^2 - 6x+\left(-3\right)^2-\left(-3\right)^2+7$

$\implies y = x^2 - 6x+9-9+7$

Factor the perfect square trinomial:

$\implies y=(x-3)^2-9+7$

$\implies y=(x-3)^2-2$

To solve the quadratic, set it to zero and solve for x:

$\implies (x-3)^2-2=0$

$\implies (x-3)^2-2+2=0+2$

$\implies (x-3)^2=2$

$\implies \sqrt{(x-3)^2}=\sqrt{2}$

$\implies x-3= \pm\sqrt{2}$

$\implies x-3+3= 3\pm\sqrt{2}$

$\implies x= 3\pm\sqrt{2}$

Therefore, the solution to the given quadratic equation is:

$x= 3+\sqrt{2}, \quad x= 3 -\sqrt{2}$

Step One: Cancel 3x and 6x.

6x/3x = 2

Step Two: Factor x^2 + 5x + 6

(x+3)(x + 2)

Step Three: Factor x^2 + 9x + 14

(x + 2)(x +7)

Answer

2*(x + 3) / (x + 7) The (x + 2 )s cancel out

The mean of 6x, 3x and 5x is the same as the mean of 40, 50 and 36. Show all work!

rodikova [14]

Answer:

x = 9

27, 45, 54

Step-by-step explanation:

The mean of 6x, 3x and 5x = 6x + 3x + 5x / 3 = 14x / 3 = 4 2/3x

The mean of 40, 50 and 36 = 40 + 50 + 36 = 126/3 = 42

4 2/3x = 42

x = 42÷14/3 = 42 * 3/14 = 9

6x = 54

3x = 27

5x = 45

Least to greatest order: 27, 45, 54

Hope this helps :)
