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)
(x - 7)(x + 2)
x times x = 25 x = 5
x = W2 - V and you cannot get any further than that since neither W nor V are known.
(x-2)(x-4) x=2,4 ans
Quadratic - the degree is two.
X= 1.567764363, -9.567764363
y=xsquared-4x+2
x times x
Take the square root of both sides. x2 = 441 So x = 21
x2+1/4x = 0 x(x+1/4) = 0 Therefore: x = 0 or x = -1/4
x times x x multiplied by itself
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 =)
