Calculator Output

9 = x
x1
Cross multiply: 9 * 1 = x * x Simplifying 9 * 1 = x * x Multiply 9 * 1 9 = x * x Multiply x * x 9 = x2 Solving 9 = x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x2' to each side of the equation. 9 + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 9 + -1x2 = 0 Add '-9' to each side of the equation. 9 + -9 + -1x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x2 = 0 + -9 -1x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -1x2 = -9 Divide each side by '-1'. x2 = 9 Simplifying x2 = 9 Take the square root of each side: x = {-3, 3}
