I have a question:

what is 4x - (9) x 103-5x^2 = 68-96/2

I cant tell whether the X is a multiplication sign or not, enjoy. Simplifying 4x + - 1 (9) * 103 + - 5x2 = (-14) Multiply - 1 * 9 4x + - 9 * 103 + - 5x2 = (-14) Multiply - 9 * 103 4x + - 927 + - 5x2 = (-14) Reorder the terms: - 927 + 4x + - 5x2 = (-14) - 927 + 4x + - 5x2 = - 14 Solving - 927 + 4x + - 5x2 = - 14 Solving for variable 'x'. Reorder the terms: - 927 + 14 + 4x + - 5x2 = - 14 + 14 Combine like terms: - 927 + 14 = - 913 - 913 + 4x + - 5x2 = - 14 + 14 Combine like terms: - 14 + 14 = 0 - 913 + 4x + - 5x2 = 0 Begin completing the square. Divide all terms by - 5 the coefficient of the squared term: Divide each side by '-5'. 182.6 + - 0.8x + x2 = 0 Move the constant term to the right: Add '-182.6' to each side of the equation. 182.6 + - 0.8x + - 182.6 + x2 = 0 + - 182.6 Reorder the terms: 182.6 + - 182.6 + - 0.8x + x2 = 0 + - 182.6 Combine like terms: 182.6 + - 182.6 = 0.0 0.0 + - 0.8x + x2 = 0 + - 182.6 - 0.8x + x2 = 0 + - 182.6 Combine like terms: 0 + - 182.6 = - 182.6 - 0.8x + x2 = - 182.6 The x term is - 0.8x. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. - 0.8x + 0.16 + x2 = - 182.6 + 0.16 Reorder the terms: 0.16 + - 0.8x + x2 = - 182.6 + 0.16 Combine like terms: - 182.6 + 0.16 = - 182.44 0.16 + - 0.8x + x2 = - 182.44 Factor a perfect square on the left side: (x + - 0.4) (x + - 0.4) = - 182.44 Can't calculate square root of the right side. The solution to this equation could not be determined
