Complete each statement in the steps to solve x2 – 6x – 7 = 0 using the process of completing the square. Isolate the constant b
Tomtit [17]
"Isolate the constant by adding 7 to both sides of the equation."
This step separates the non-squareable 7 and the squareable x^2 - 6x .

"Add 9 to both sides of x^2 - 6x = 7 to form a perfect square trinomial while keeping the equation balanced."
After separating the non-squareable, add the number which makes the first or left side a perfect square trinomial. The formula to find the number is: c =  {\frac{b}{2}  }^{2} .
When we plug the values: c =  { \frac{ - 6}{2} }^{2}
Simplify: c =  {( - 3)}^{2}  = 9

"Write the trinomial x^2 - 6x + 9 as (x - 3) squared."
When you factor x^2 - 6x + 9 , you will get (x - 3) \times (x - 3) .

"Use the square root property of equality to get x - 3 = ±  \sqrt{16} ."
The 16 is coming from the part when we add 9. We needed 9 on the left side for a perfect square, but to protect the balance of the equality, we need to add 9 to the right side too. When we add 7 and 9, we got 16, and that is where it came from.

"Isolate the variable x to get solutions of -1 and 7."
To isolate x we branched the plus-minus sign:
x - 3 = 4 \: \:  \:  x = 4 + 3 = 7 \\  \\ x - 3 =  - 4 \:  \:  \: x =  - 4 + 3 =  - 1

Convert into slope-intercept form<br><br> x+y=6
puteri [66]
<h3>Answer:   y = -x + 6</h3>

To get this answer, you subtract x from both sides to go from x+y = 6 to y = 6-x which rearranges to y = -x+6

Note that y = -x+6 is the same as y = -1x+6

We can compare this to y = mx+b form to see that m = -1 is the slope and b = 6 is the y intercept.
