Question

Medal & fan.
Determine the solution set of (x + 2)^2 = 36.
Would i use foil here?

Answer 1

Take square root of both sides.

Answer 2

you will wind up with two equations to solve
x+2=6 or x+2=-6

Answer 3

x=4 or x=-4?

Answer 4

Yes, x = + or - 4 [Also known as -4,4]

Answer 5

answer choices are:
a.) (6,-8)
b.) (4,-8)
c.) (4,-6)

Answer 6

What is the square root of 36?

Answer 7

\[\pm6\]

Answer 8

in this case negative

Answer 9

So find what x+2 = 6 and x-2 = 6, solve and you get, x=4, and x=8

Answer 10

its for sure positive 8?

Answer 11

4,-8

Answer 12

oh okay

Answer 13

\[x+2=6 \text{ or } x+2=-6 \\ \text{ subtracting 2 on both sides gives } \\ x=6-2 \text{ or } x=-6-2 \\ x=4 \text{ or } x=-8\]

Answer 14

not 8

Answer 15

pluggin in 8 yields (8+2)^2=36 which is not a true equation

Answer 16

(4+2)^2=36 is true
(-8+2)^2=36 is also true
