So the problem is: Solve: 4x2 - x = 3
Solve 3x = 33
Set it equal to 0 and subtract x and solve for y
x2 + 4x + 1 = 0 add and subtract 3 to both sides to complete the square x2 + 4x + 4 = 3 form the square (x + 2)2 = 3 take the square root of both sides x + 2 = ± √3 subtract 2 to both sides x = -2 ± √3
Here is how you solve this. You call your number "x", and write:x = 0.5454... 100x = 54.5454... Then you subtract the first equation from the second, and solve the resulting equation for "x". This will give you "x" as a fraction. Simplify as appropriate.
U can subtract 18 from each side of the equation.
A normal 3x3 magic square has a sum of 15. So you subtract 3 from each number in the square.
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.
Subtract the average from highest result subtract the smallest result from average pick the highest number of two numbers put the symbol plus or minus TA DA that's your error
Let the number be x and so if: (2x-6)/2 = 20 then x = 23
I put the larger number above the smaller number and then I subtract. 719 423 ----- 296
2 and 1 You can solve this by trial and error x^2 - y^2 = 3 If x = 2 and y = 1 then 4-1 = 3 Nothing else will work
To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.
Let x represent the unknown number and use the known numbers to solve. Set up the equation: x + 9 = 15 (subtract 9 from each side to solve for the unknown number) x = 6

to solve 18-70 you would subtract just like any other equation. 18-70 is equal to a negative number, -52.
Solve 3x = 33
