Simplifying mx2 + -1x(x + 4) + 2 = 0 Reorder the terms: mx2 + -1x(4 + x) + 2 = 0 mx2 + (4 * -1x + x * -1x) + 2 = 0 mx2 + (-4x + -1x2) + 2 = 0 Reorder the terms: 2 + mx2 + -4x + -1x2 = 0 Solving 2 + mx2 + -4x + -1x2 = 0 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + mx2 + -4x + -2 + -1x2 = 0 + -2 Reorder the terms: 2 + -2 + mx2 + -4x + -1x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + mx2 + -4x + -1x2 = 0 + -2 mx2 + -4x + -1x2 = 0 + -2 Combine like terms: 0 + -2 = -2 mx2 + -4x + -1x2 = -2 Add '4x' to each side of the equation. mx2 + -4x + 4x + -1x2 = -2 + 4x Combine like terms: -4x + 4x = 0 mx2 + 0 + -1x2 = -2 + 4x mx2 + -1x2 = -2 + 4x Add 'x2' to each side of the equation. mx2 + -1x2 + x2 = -2 + 4x + x2 Combine like terms: -1x2 + x2 = 0 mx2 + 0 = -2 + 4x + x2 mx2 = -2 + 4x + x2 Divide each side by 'x2'. m = -2x-2 + 4x-1 + 1 Simplifying m = -2x-2 + 4x-1 + 1 Reorder the terms: m = 1 + -2x-2 + 4x-1
