2 or -1

2. 2 squared = 4, and 4-2 = 2

7 subtracted from the quotient of a number and 2 is a -6

22 - 2 = 2. The number is therefore 2.

2

The number is 5.

7 - from the quotient of a number and 2 is -6

The number that when multiplied by 3, then 4 is subtracted and 2 added and the answer is 16 would be 6 .

18-12 = 6 and 12/2 = 6

The algebraic equation becomes x2 - x = 2 (or) x2 - x - 2 = 0 This has the solution (x-2)(x+1) = 0 so the answer is either 2 or -1.

2 square numbers subtracted from each other to make 8 = -6

7 is.

multiply the same number with the question. the result is square number. for eg: given number is 2. we want to multiply the number with 2. answer is 4. square for 2 is 4.

1,085 - 61 = 1,024 = (32)2

The number is 8.... 7 x 8 = 56.... 2 x 8 = 16... 56 - 16 = 40

3

No.

3-2x=7 so -2x=4 and x=-2

60

⅔ a number - 9 = 7 → ⅔ a number = 7 + 9 = 16 → the number is 16 × 3/2 = 24.

2 (two)

A perfect square is the result of a number being multiplied by itself. For instance, 9 is a square number as it is the result of 3x3. If a number is a square, its factors can all be paired up. In the case of 24, its prime factors are 2, 2, 2 and 3. While two of the 2s can pair up, there is another 2 and a 3 left over. Thus, we can say for certain that 24 is not a square.

Suppose the number is x Then x - sqrt(2x) = 4 x - 4 = sqrt(2x) Squaring both sides: x2 - 8x + 16 = 2x So that x2 - 10x + 16 = 0 Factorising: (x - 2)(x - 8) = 0 So x = 2 or x = 8. Remember that sqrt(4) can also be -2.
