2(x+7)3X
I think... look it up though to be sure
Answer:
x = i√3, -i√3
Step-by-step explanation:
Simply take the root of both sides, then solve.
Answer:
The solutions to the quadratic equations will be:

Step-by-step explanation:
Given the expression

Let us solve the equation by completing the square

Add (-6)² to both sides

simplify

Apply perfect square formula: (a-b)² = a²-2ab+b²
i.e.

so the expression becomes


solve

add 6 to both sides

Simplify

also solving

add 6 to both sides

Simplify

Therefore, the solutions to the quadratic equation will be:

5*9=45
1*9=9
Then add both numbers together
45+9=54
I believe it's the 3rd one
