What number completes square x2 plus 10x equals 31?
-6
What number is needed to complete the square x2 23x equals 0?
x2 23x equals 0
What number must you add to complete the square of x2 minus14 equals 7?
Since there are only terms in x2 and constants, but none in x, completing the square is not an option! x2 - 14 = 7 x2 = 21 and so x2 = sqrt(21)
What number do you add to complete the square x2 plus 10x?
25
What does forty nine is the square of a number mean?
To square a number (mathematically expressed as X2) you multiply it by itself. 49 is the square of the number 7, and 7 can be said to be the 'square root' of 49.
What number completes square x2 plus 10x equals 31?
-6
What number must be added to the polynomial to complete the square x2 - 20x?
Adding 100 completes the square. { I wonder why you want to complete the square when the expression already factors as x(x-20) }.
What number completes the square of x2 plus 14x equals -7?
Since the first coefficient is already equal to 1, just take half the second coefficient (half of 14), then square the result. This must be the constant term on the left side.
What number is needed to complete the square x2 23x equals 0?
x2 23x equals 0

The cube of a number equals the square of the same number find the number?
x3=x2 x3-x2=0 Factor out x2 x2(x - 1) = 0 If x2=0 then x=0. If x - 1 = 0 then x = 1. Therefore the number is 0 or 1.

When you square my value and and subtract it from 23 the result is the square root of 36 I am an irrational number What is my number?
23 - x2 = sqrt(36) 23 - x2 = ±6 x2 = 17 or 29 So x Î {-5.385, -4.123, 4.123, 5.385} approx
What are the examples of an perfect square trinomial?
x2 + x + 1/4 x2 + 2x + 1 x2 + 4x + 4 In each case, the number on the right is one-half the number in the middle, squared.
What is the square of a natural number?
The square of a number is the result obtained by multiplying the number by itself. The operation is known as squaring the number. The name comes from the fact that the area of a square is the square of one its sides. An expression such as x2 is usually read as x-square,
