The expression is: x² + 2
An expression such as root(3) + 2 (square root of 3, added to 2) can not be simplified. Of course, you can convert the square root to a decimal and then add, to get an approximate result.
To add simplified square roots, first simplify each individual square root expression. Then, if the numbers inside the square roots are the same, add or subtract the numbers outside the square roots. Finally, combine the numbers inside the square roots if possible. For example, to add √8 and √18, simplify them individually as 2√2 and 3√2. Since the numbers inside the square roots are the same, add 2 and 3 to get 5√2 as the final result.
To complete the square of x^2 + 6x + 17, you need to add (6/2)^2 = 9 to the expression. This is because half of the coefficient of x is 6/2 = 3, and squaring that gives you 9. So the completed square is x^2 + 6x + 9 + 17 = (x + 3)^2 + 17.

There is no "general" equation. The square root of a number (or expression) is simply sqrt(x) or x1/2, where x is a number or an expression. In more basic mathematics, x must be non-negative but, once you start studying complex numbers, that is no longer a requirement.

your expression is this... x + -10 = 2 x = 12 You need a 12 to add to -10 to get 2
Subject: Algebra Topic: Expression Evaluation Step 1: Let the number be represented by the variable ( x ). Step 2: Write the expression for "a square of a number": ( x^2 ). Step 3: Write the expression for "3 less than a square of a number": ( x^2 - 3 ). Step 4: Provide the final answer: The expression representing "3 less than a square of a number" is ( x^2 - 3 ). Explanation: The expression ( x^2 - 3 ) represents the result of subtracting 3 from the square of a given number ( x ).

Multiply the entire expression by a least common multiple and then simplify the expression. In this case, the least common multiple is 30 so multiply the entire expression by 30 and simplify.
