You want to create an equation for this. The equation should look like this: x^2 - 2x + 4 = 0 Use the quadratic equation to solve it.
Standard deviation is equal to the square root of the variance. To arrive at this work out the mean, then subtract the mean and square the result of each number. Then work out the mean of those squared differences and take the square root of that.
when you subtract one square number with another the answer is 16 what are the two numbers
There aren't any whole numbers that satisfy this.
The result :)
So the problem is: Solve: 4x2 - x = 3
The number subtracted is 16 (42). The other square number is 25 (52). *If you include zero, the pair 9 (32) and 0 (02) also fits the equation.
The roots are 4 and 5. If you subtract the square number 16 (4X4) from the square number 25 (5X5), you would get 9.
4 and 9
9, the square of 3, and 4, the square of 2
5 and 2
1 and 36
16 and 4
Completing the square is a method to solve quadratic equations. To use this method you take the number without a variable and subtract it from both sides, so that it is on the opposite side of the equation. Then add the square of half the coefficient of the x-term to both sides. This will give you a perfect square equation to solve for.
It is 243.
That isn't possible.
4 and 3
324 - 289 = 35
1 and 4?
9 and 25
18 and 17.
The square numbers are: 16-4 = 12
