Question

What value is added to both sides of the equation x2 – 6x = 10 in order to solve by completing the square?

Answer 1

\[x^2-6x=10 ?\]

Answer 2

yess !

Answer 3

the answer is decimal, take a litle longer to solve

Answer 4

\[(x-3)^2=10+3^2\]\[x-3=\pm \sqrt{19}\]\[x=3\pm \sqrt{19}\]

Answer 5

\[\frac{6}{2}=3,3^2=9\]

Answer 6

there are a nother way to solve

Answer 7

\[x^2-3x +9=10+9\]

Answer 8

Add 9 to both sides to complete the square.

Answer 9

\[x^2-6x+9=10+9\]

Answer 10

\[(x-3)^2=19\]

Answer 11

yes,2 way can solve I like the frist way I solve it short cut and faster

Answer 12

\[x-3=\pm \sqrt{19}\]

Answer 13

\[x=3\pm \sqrt{19}\]
