Best ResponseYou've already chosen the best response.0Simplifying (x + 9)(x + 8) Reorder the terms: (9 + x)(x + 8) Reorder the terms: (9 + x)(8 + x) Multiply (9 + x) * (8 + x) (9(8 + x) + x(8 + x)) ((8 * 9 + x * 9) + x(8 + x)) ((72 + 9x) + x(8 + x)) (72 + 9x + (8 * x + x * x)) (72 + 9x + (8x + x2)) Combine like terms: 9x + 8x = 17x (72 + 17x + x2)
