Answer:
x + 5 * 2x - 1
Step-by-step explanation:
(5x² + 3x - 1)-(3x² - 6x+4)
remove parenthesis
5x² + 3x - 1 - 3x² + 6x - 4
collect the terms and calculate
2x² + 9x - 5
write as a difference
2x² + 10x - x - 5
factor and then factor out the negative sign
2xx (x+5) - x - 5
2xx (x+5) - (x+5)
factor out (x+5)
(x+5) * (2x - 1) is the solution
