Simplifying (3x + 2)(7x + -4) = 21x2 + 10 Reorder the terms: (2 + 3x)(7x + -4) = 21x2 + 10 Reorder the terms: (2 + 3x)(-4 + 7x) = 21x2 + 10 Multiply (2 + 3x) * (-4 + 7x) (2(-4 + 7x) + 3x * (-4 + 7x)) = 21x2 + 10 ((-4 * 2 + 7x * 2) + 3x * (-4 + 7x)) = 21x2 + 10 ((-8 + 14x) + 3x * (-4 + 7x)) = 21x2 + 10 (-8 + 14x + (-4 * 3x + 7x * 3x)) = 21x2 + 10 (-8 + 14x + (-12x + 21x2)) = 21x2 + 10 Combine like terms: 14x + -12x = 2x (-8 + 2x + 21x2) = 21x2 + 10 Reorder the terms: -8 + 2x + 21x2 = 10 + 21x2 Add '-21x2' to each side of the equation. -8 + 2x + 21x2 + -21x2 = 10 + 21x2 + -21x2 Combine like terms: 21x2 + -21x2 = 0 -8 + 2x + 0 = 10 + 21x2 + -21x2 -8 + 2x = 10 + 21x2 + -21x2 Combine like terms: 21x2 + -21x2 = 0 -8 + 2x = 10 + 0 -8 + 2x = 10 Solving -8 + 2x = 10 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + 2x = 10 + 8 Combine like terms: -8 + 8 = 0 0 + 2x = 10 + 8 2x = 10 + 8 Combine like terms: 10 + 8 = 18 2x = 18 Divide each side by '2'. x = 9 Simplifying x = 9
