What is the intermediate step in the form (x + a)2 = b as a result of completing the

Eddi Din [679]

Answer:

(x + 7)^2 = 64

Step-by-step explanation:

x^2 + 23x – 19 = 9x - 4

x^2 + 23x - 9x = -4 + 19

x^2 + 14x = 15 = 0

Completing the square:

(x + 14/2)^2 - (14/2)^2 = 15

(x + 7)^2 - 49 = 15

(x + 7)^2 = 64

What value is added to both sides of the equation x2 − 2x = 10 in order to solve by completing the square?

VLD [36.1K]

Hi,
Answer C

$x^2-2x=10\\
x^2-2x+1=10+1\\

\Rightarrow\ (x-1)^2=11\\
\Rightarrow\ (x-1)^2-11=0\\
\Rightarrow\ (x-1)^2-( \sqrt{11})^2=0\\
\Rightarrow\ ((x-1)+ \sqrt{11})((x-1)- \sqrt{11})=0\\
\Rightarrow\ x-1+ \sqrt{11}=0\ or\ x-1- \sqrt{11}=0\\

\Rightarrow\ x=1- \sqrt{11}\ or\ x=1+ \sqrt{11}\\
