How to solve for x in x² + 4x + 4 = 8 Explanation will get brainliest. Thanks guys!

x=−2±2√2

x=−2±4√ 2

x=−4±2√ 2

x=−4±4√ 2

x = -2 ±2sqrt(2)

Step-by-step explanation:

x² + 4x + 4 = 8

Lets solve by completing the square

The left is set for completing the square since (4/2)^2 =4  so we rewrite this as (x+4/2)^2

(x+2) ^2 = 8

Take the square root of each side

sqrt((x+2) ^2 ) = ±sqrt(8)

x+2 =±sqrt(4*2)

x+2  =±sqrt(4)sqrt(2)

x+2 = ±2sqrt(2)

Subtract 2 from each side

x+2-2 = -2 ±2sqrt(2)

x = -2 ±2sqrt(2)

Steps to solve:

x² + 4x + 4 = 8

~Subtract 8 to both sides

x² + 4x + 4 - 8 = 8 - 8

~Simplify

x² + 4x - 4 = 0

This is in standard form [ ax² + bx + c ], so we can find the a, b,  and c values.

a = 1

b = 4

c = -4

Use the quadratic formula [ ] to solve.

Therefore, the correct answer is x = −2 ± 2√2 (Option A)

Best of Luck!

it could be 1,3 and more others to create a cylinder.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
