Simplifying (2x + 1)(x + -5) = 2x2 + -1 Reorder the terms: (1 + 2x)(x + -5) = 2x2 + -1 Reorder the terms: (1 + 2x)(-5 + x) = 2x2 + -1 Multiply (1 + 2x) * (-5 + x) (1(-5 + x) + 2x * (-5 + x)) = 2x2 + -1 ((-5 * 1 + x * 1) + 2x * (-5 + x)) = 2x2 + -1 ((-5 + 1x) + 2x * (-5 + x)) = 2x2 + -1 (-5 + 1x + (-5 * 2x + x * 2x)) = 2x2 + -1 (-5 + 1x + (-10x + 2x2)) = 2x2 + -1 Combine like terms: 1x + -10x = -9x (-5 + -9x + 2x2) = 2x2 + -1 Reorder the terms: -5 + -9x + 2x2 = -1 + 2x2 Add '-2x2' to each side of the equation. -5 + -9x + 2x2 + -2x2 = -1 + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -5 + -9x + 0 = -1 + 2x2 + -2x2 -5 + -9x = -1 + 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -5 + -9x = -1 + 0 -5 + -9x = -1 Solving -5 + -9x = -1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + -9x = -1 + 5 Combine like terms: -5 + 5 = 0 0 + -9x = -1 + 5 -9x = -1 + 5 Combine like terms: -1 + 5 = 4 -9x = 4 Divide each side by '-9'. x = -0.4444444444 Simplifying x = -0.4444444444
