The equation "1/2x^2 = x" can be rewritten as "x^2 - 2x = 0" by multiplying both sides by 2 to eliminate the fraction. This equation can be factored as x(x-2) = 0, leading to solutions x=0 and x=2. Therefore, the values of x that satisfy the original equation are x=0 and x=2.
X = √63
2 x cosine squared x -1 which also equals cos (2x)
Half of 2x squared is x squared. To find half of a term, you divide the coefficient by 2 and keep the variable and exponent the same. In this case, half of 2 is 1, so the expression simplifies to x squared.
(2, -2)
If x squared = 5 then x = sqrt(5) = ± 2.2361 (approx).
X = √63
no, because xx=x squared, and x squared is not linear

Yes
X squared = x+6 6+x=x squared X=6
2.645 squared equals 7. Save --------- Unclear what you're asking: If x=7, then x^2 (that is, "x squared") equals 49. or If x^2=7, then x equals the square root of 7, or about 2.64575

Well pythagorus theoreum is a squared plus b squared equals c squared and circumference equals pie x diameter and area equals pie x radius squared

"x squared equals to 25" is not an inequality! You need to re-think the question!
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
