Can a non-radical number be added to a radical?
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.
How do you add simplified square roots?
You can add simplified square roots only if the radicals are the same and, in that case, you treat the radicals as you would treat a variable in algebra.For example, sqrt(18) + sqrt(50)= sqrt(9*2) + sqrt(25*2)= 3*sqrt(2) + 5*sqrt(2)= [3 + 5]*sqrt(2)= 8*sqrt(2)
How do you write expression double 2 and then add 5?
To write the expression for double 2 and then add 5, you first calculate double 2, which is (2 \times 2 = 4). Then, you add 5 to this result: (4 + 5). The complete expression is ( (2 \times 2) + 5 ), which simplifies to 9.
What number must you add to complete the square of x2 6x17?
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.
How do you write the expression double 2 and then add 5?
To write the expression for doubling 2 and then adding 5, you first multiply 2 by 2, which gives you 4. Then, you add 5 to that result. The full expression can be written as ( (2 \times 2) + 5 ), which simplifies to ( 4 + 5 ), resulting in 9.

3 less than the square of a number?
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 ).
What is the general equation square root?
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.
What number must be added to x2 8x to complete the square?
To complete the square for the expression ( x^2 + 8x ), first take half of the coefficient of ( x ) (which is 8), square it, and add it. Half of 8 is 4, and squaring it gives ( 4^2 = 16 ). Therefore, the number that must be added to ( x^2 + 8x ) to complete the square is 16. Thus, the completed square form is ( (x + 4)^2 ).
How do you solve 4 square root 6 plus 3 square root 2 minus 2 square root 5?
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.
