You don't. There's no question there, and nothing that needs solving.
If it were equal to something, then we could get some exercise figuring out
what number 'x' must be in order to make it true. But the way it is now, it
doesn't say anything. It's just a number that depends on what 'x' is.
x = 1/2 [ 1 ± i sqrt(7) ]
You have to put your heart into it!
If x squared -10 = 0 then x = the square root of 10
The question contains an expression, not an equation or inequality. There is nothing to solve in an expression.
Solve using the quadratic formula
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
x = 1/2 [ 1 ± i sqrt(7) ]
x^(2) - 4y^(2) Before calculating , we note #1 ' There is a negative sign between the two squares. So it will factor #2 ' '4' is the square of '2' . So we can redraw the terms as ( 2y)^2 Hence x^(2) - (2y)^2) This now satisfies the two conditions above. . So it will factor to ( x - 2y)(x + 2y) Note the different signs in each bracket . You hve asked for it to be solved!!! To solve you need to equate the terms to a value. In this case use '0' Hence (x - 2y)(x + 2y) = 0 Taking each bracket in turn x - 2y = 0 x = 2y or 2 = x/y or y = x/2 Then x + 2y = 0 x = -2y or -2/x/y or y = x/-2 Are the possible forms of solution. NB If you have two squared terms and a positive (+) between them, then it does NOT factor. NNB Think of the Pythagorean Equation a^2 + b^2 = h^2 This DOES NOT factor. However a^2 = h^2 - b^2 (Algebraic rearrangement) , DOES factor to a^2 = (h - b)(h + b)
X=1
That factors to (x + 1)(x - 3) x = -1, 3

The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
whp do you do a 7 suared
Solve this problem -x squared -40x- 80 =0
If x squared -10 = 0 then x = the square root of 10
