Start by factoring out the GCF, which is 3x:
3x(3x^2 + 2x - 1). Then factor the trinomial 3x^2 + 2x -1:
3x(3x-1)(x+1)
First, minus salary
paycheck=comission+salary
paychec-salary=comision
6500-1000=5500
comission/sales=5500/45000=0.122222222/1
pecent means parts ou fo 100
x%=x/100
0.122222/1 times 100/100=12.2222/100=12.222%
about 12%
