Question

Complete the square to transform the quadratic equation into the equation form (x – p)2 = q. x2 + 14x + 34 = 5

Answer 1

Answer:

B) (x + 7)^2 = 20

Step-by-step explanation:

You can subtract 34 from the original equation to get

Now, you can add the square of half the x-coefficient, and you will have ...

... x^2 +14x +49 = -29 +49

... (x +7)^2 = 20 . . . . . . matches selection B
