Lamar is solving the equation x2−12x=−6 by completing the square. Which shows Lamar's next step and the solution to the equation?

Step 1: x^2 - 12x = -6

Step 2: x^2 - 12x + 36= -6 + 36

Answers

Completing the square is a process to find the solutions, or the x-values, to a quadratic equation. This method can only work if it is in the format: x^2 + bx = c
In this equation, the b value is -12 and the c value is -6. The process for completing the square goes like this:

x^2 + bx + (b/2)^2 = c + (b/2)^2

Now let’s solve the equation above using this method.

Step 1: x^2 - 12x + (-12/2)^2 = -6 + (-12/2)^2

Step 2: x^2 - 12x + (-6)^2 = -6 + (-6)^2

Step 3: x^2 - 12x + 36 = -6 + 36

Step 4: x^2 - 12x + 36 = 30

Now, to factor it. After doing the process until now, the left side of the equation can ALWAYS be in the format: (x + a)^2

Step 5: x^2 - 12x + 36 can be factored in this format as (x - 6)^2

Step 6: (x - 6)^2 = 30

Step 7: x - 6 = √30

Step 8: x = 6 ±√30

5x + y = 11
3x − y = 9

Answers

Answer:

x = 5/2y = -1.5

Step-by-step explanation:

5x + y = 11

        3x − y = 9

=> 5x + y = 11

           +3x − y = +9

=> 8x = 20

=> x = 20/8

=> x = 5/2

=> 5(5/2) + y = 11

=> 25/2 + y = 11

=> 12.5 + y = 11

=> y = 11 - 12.5

=> y = -1.5

Therefore, the answers are:

x = 5/2y = -1.5

He should have paid attention when his father taught the family to read the position of the sun. He should have paid attention, too, before sneaking off this morning on his first solo hike, forgetting the whistle his mother stressed he always bring.He pictured his parents now at their camp beneath the tree with the eagles nest, wondering where he was. Randall was wondering the same thing. Lost and out of food, he feared he had but a few hours before darkness closed in, trapping him in the bitter cold with the creatures of the night.He closed his eyes to fight back tears, when he heard it in the distance. Water! His fathers words came flowing into his mind; one tip he actually remembered. If youre ever lost, find a river and follow it.In a flash, he was on his feet, scaling fallen trees, tearing through brush, frantically following the sound. The sky grew darker, but the noise grew louder, and Randall, tired and scared, forged ahead until he found it. He reached the river bank and was mulling his next move when a sudden splash caught his eye.A majestic eagle rose from the water, soaring skyward with a freshly caught fish in its talons. Could it be the same eagle nested above his camp? It glided triumphantly into a high nest a short distance away, eager to greet its family. Randall smiled, equally triumphant, eager to do the same as he followed the eagles flight.In the distance, he saw his mother, his whistle clutched in her hand.
