x = -3
Subtract 2 from both sides.
x - 2 = -3 - 2
x - 2 = -5

What are the roots of x2 plus 6x plus 12 equals 0?
x2 + 6x + 12 = 0 x2 + 6x + 9 = -3 (x + 3)2 = -3 x + 3 = ± √-3 x = -3 ± i√3
X2 plus 7x plus 9 equals 3?
x2 + 7x + 9 = 3 ∴ x2 + 7x + 6 = 0 ∴ (x + 6)(x + 1) = 0 ∴ x ∈ {-6, -1}
Evaluate the derivative of the given function at the given point y equals x2 - x equals 3 y equals 6?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y)2. Also, If y = x2 - x then what = 3? If y = x2 and - x = 3 then y = 6 is inconsistent with the equation of the function.
How do you evaluate expression 0.2 x n for n equals 3 and n equals 6?

X2-8x plus 15 equals 0?
x2 - 8x + 15 = 0 can be factored as (x - 3)(x - 5) = 0 : This holds true when one or both of the terms in brackets equals zero. When x - 3 = 0 then x = 3 When x - 5 = 0 then x = 5.
Answer to -x2 equals x-6?
-x2 = x - 6 x2 + x - 6 = 0 (x - 2)(x + 3) = 0 x ∈ {-3, 2}
X2 - x - 6 equals?
-4
Evaluate the function fx equals -x2 plus 5 for x equals 4?
Interpreting the question as "evaluate f(x) = -x2 + 5 for x = 4". This is the same as asking "what is f(4)". To evaluate f(4) just replace each instance of the x in the definition of f(x) by the number 4: f(4) = -42 + 5. The result is -11.
If fx equals x2 then fx-1 equals?

X2 - x - 6 equals 0?
x2 - x - 6 = (x - 3)(x + 2) = 0; whence, x = 3 or -2.
How do you solve x2-2x-3 equals 0?
x2-2x-3 = 0 (x+1)(x-3) = 0 x = -1 or x = 3
Which of the numbers are solutions to the equation x2 equals 3?
If: x2 = 3 Then: x = square root of 3
What is x2 plus 2x-15 equals?
x2 + 2x - 15 = (x - 3)(x + 5)
2x equals x2 plus 4x-3?
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
What is the solution to the equation x2 plus 3 equals 124?
x2+3=124 x2=121 x= square root(121) x=11
X2 plus 4x - 9 equals 5x plus 3?
x2 + 4x - 9 = 5x + 3 ∴ x2 - x - 12 = 0 ∴ (x + 3)(x - 4) = 0 ∴ x ∈ {-3, 4}
When factored completely x2 9 equals?
-7
