5(x+3)(x+2)-3(x2+2x+1)
mr Goodwill [35]

[ Answer ]

\boxed{5x^{2} \ + \ 13x \ + \ 27}

[ Explanation ]

  • Simplify: 5(x + 3)(x + 2) - 3(x2 + 2x + 1)

--------------------------------------

  • Add Similar Elements: 2x + 2x = 4x

5(x + 3)(x + 2) - 3(4x + 1)

  • Expand: 5(x + 3)(x + 2) - 3(4x + 1): 5x^{2} + 25x + 30

5x^{2} + 25x + 30 - 3(4x + 1)

  • Expand: - 3(4x + 1): -12x - 3

5x^{2} + 25x + 30 - 12x - 3

  • Simplify: 5x^{2} + 25x + 30 - 12x - 3: 5x^{2} + 13x + 27

= 5x^{2} + 13x + 27

\boxed{[] \ Eclipsed \ []}
