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}\\

For the following system if you isolated X in the second equation to use the substitution method what expression would you subst

Anestetic [448]

Option A. зу + 12 is the right answer

Step-by-step explanation:

The substitution method consists of finding the value of a variable from one equation and then putting it into another equation to find the value of other variable.

Given equations are:

$2x+y=8\\-x-3y=-12$

We have to isolate x in the 2nd equation

$-x-3y=-12$

Multiplying equation by -1

$x+3y=12$

Subtracting 3y from both sides

$x+3y-3y=12+3y\\x=12+3y$

Hence,

Option A. зу + 12 is the right answer
