Question

1. multiply (2n^2+5n+4)(2n-4)
2. multiply (2n+2)(2n-2)

Answer 1

1) 2n^2*2n + 5n*2n + 4*2n - (2n^2*4) - (5n*4) - (4*4)

2) 2n*2n + 2n*2 - (2n*2) - (2*2)

Answer 2

Haha ya thats wrong because thats not even an option

Answer 3

well obviously, you have to simplify

Answer 4

o i forgot with the two questions you are trying to find a simpler way of writing them

Answer 5

yes, i expanded it out for you, now all you have to do is add and subtract like terms

Answer 6

1. \[\large (2n^2+5n+4)(2n-4)\]\[\large \color{green}{2n}(2n^2 +5n + 4)-\color{green}4(2n^2+5n+4)\]\[\large (2n)(2n^2) +(2n)(5n)+(2n)(4) - 4(2n^2) -4(5n)-4(4)\]2.
\[\large (2n+2)(2n-2)\]\[\large \color{green}{2n}(2n-2) +\color{green}2(2n-2)\]\[\large (2n)(2n)-(2n)(2)+2(2n)-2(2)\]
