Best ResponseYou've already chosen the best response.1we have to distribute every one of the numbers in the first parenthesis by every number in the second parenthesis. (x^2 + 2x  3)(4x^2  5x + 6) x^2(4x^2  5x + 6) 4x^4  5x^3 + 6x^2 now the 2nd number 2x(4x^2  5x + 6) 8x^3  10x^2 + 12x now the 3rd number 3(4x^2  5x + 6) 12x^2 + 15x  18 now put them all together 4x^4  5x^3 + 6x^2 + 8x^3  10x^2 + 12x  12x^2 + 15x  18 combine like terms 4x^4 + 3x^3  16x^2 + 27x  18 <== your answer

Best ResponseYou've already chosen the best response.0@HelloKitty17 If you'd like to understand how to find the product, complete the grid and you'll get the correct answer. If you want just the answer, read through what @OregonDuck spent his/her valuable time to write, and you'll find the answer somewhere.
