Xsquared - v equals wsquared what is X how did you work this out?
Yugiohgx114
It is not possible to solve for a value of X since there are three unknowns, X, v and W and only one equation. All that can be done is to make x the subject of the equation - that is, to express X in terms of the other two variables.
X2 - v = W2
X2 = W2 + v
X = +/- sqrt(W2 + v)

Xsquared equals 5x plus 14?
(x - 7)(x + 2)
What is the factor of xsquared equals 25?
x times x = 25 x = 5
What is V plus x equals Wsquared what is x?
x = W2 - V and you cannot get any further than that since neither W nor V are known.
Solve xsquared - 6x plus 8 equals 0?
(x-2)(x-4) x=2,4 ans
Is y equals x-xsquared plus 3 quadratic or linear?
Quadratic - the degree is two.
What is Xsquared equals -8x plus 15 using the quadratic formula?
X= 1.567764363, -9.567764363
How do you graph y equals x squared -4x plus 2?
y=xsquared-4x+2
How do you solve xsquared equals 441?
Take the square root of both sides. x2 = 441 So x = 21
What does xsquared equal?
x times x
How do you solve xsquared plus 1over4x equals 0?
x2+1/4x = 0 x(x+1/4) = 0 Therefore: x = 0 or x = -1/4
What is xsquared?
x times x x multiplied by itself
How do you factor xsquared plus 2x-3?
find factors of -3 (3 & -1 ) also add together to get 2 (for the 2x part) put x on both sides (x+3) (x-1) << because xsquared means x times x check it 3 times -1 = -3 3 times x = 3x -1 times x = -1x x times x = xsquared = xsquared + 2x -3 hope this helped =)
