Which three steps are correct when solving this quadratic equation by completing the square? X^2-10x=39
sergey [27]

Step-by-step explanation:

Any answer that involes,

Step 1: Complete the Square

{x}^{2}  - 10x = 39

( \frac{  - 10}{2} ) {}^{2}  = 25

{x}^{2}  - 10x + 25 = 64

Step 2: Turn the left side into a binomial

(x - 5) {}^{2}  = 64

Step 3: Solve for x.

x - 5 = +  -  8

x - 5 = 8

x = 13

OR

x - 5 =  - 8

x =  - 3

X=-3 or X=13

Solve the inequality <br> 3(x – 2) + 1 ≥ x + 2(x + 2)
leva [86]

Answer:

No solution.

Step-by-step explanation:

Step 1: Write inequality

3(x - 2) + 1 ≥ x + 2(x + 2)

Step 2: Solve for <em>x</em>

  1. Distribute: 3x - 6 + 1 ≥ x + 2x + 4
  2. Combine like terms: 3x - 5 ≥ 3x + 4
  3. Add 5 to both sides: 3x ≥ 3x + 9
  4. Subtract 3x on both sides: 0 ≥ 9

Here we see that the statement is false. Therefore, you cannot solve for the inequality.
