27-x^2=0

Answer 1

Simplifying
(x2) + -27 = 0
x2 + -27 = 0

Reorder the terms:
-27 + x2 = 0

Solving
-27 + x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '27' to each side of the equation.
-27 + 27 + x2 = 0 + 27

Combine like terms: -27 + 27 = 0
0 + x2 = 0 + 27
x2 = 0 + 27

Combine like terms: 0 + 27 = 27
x2 = 27

Simplifying
x2 = 27

Take the square root of each side:
x = {-5.196152423, 5.196152423}
