Theo started to solve the quadratic equation (x + 2)2 – 9 = –5. he added 9 to both sides and the resulting equation was (x + 2)2 = 4. next, he took the square root of each side. which was the resulting equation of that step? x + 2 = ±4 x + 2 = ±2 x + 2 = ±8 x + 2 = ±16

x+2=±2

Step-by-step explanation:

Here the original equation was:

Then Theo added 9 to both the sides to get,

After this he took square root of each side,

So this simplifies to

x+2=±2

 option B

(B)  x + 2 = ±2

Step-by-step explanation:

the 3rd option is right

step-by-step explanation:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
