No, it equals 28.
x = √(2-x) x2 = 2-x x2 + x = 2 x2 + x - 2 = 0 (x+2)(x-1) = 0 x = 1 or -2
x=2*5 x=10
x = 2 is an algebraic equality (Because there is an 'equals'(=) sign) x - 2 is an algebraic expression ( Because there is NO equals sign).
x=-1/2
x + 3 = 2x 3 = x x cannot be 2
x = -2
x=-2
x = -2
12
f(x) = 2*(x-3)*(x+2)/(x-1) for x ≠1
If x - 4y = 2 and x + 4y = 2 then the only solution is when y = 0 and thus x = 2.
