Question

The expression below is the factorization of what trinomial?

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

Answer 1

?

Answer 2

multiply them! :)
distribute the terms of both parenthesis:
\[(5x+4)(2x-5)\]distribute the \(5x\) to \(2x\) and \(-5\) and the 4 to \(2x\) and \(-5\):\[[(5x\times2x)+(5x\times-5)+(4\times2x)+(4\times-5)]\]multiply:\[[(10x^2)+(-25x)+(8x)+(-20)]\]combine:\[10x^2-25x+8x-20\]simplify\[\large10x^2-17x-20\]
hope that helps! :)
