I hope this helps you
y= 4x^2-19x-5
4x +1
x -5
y=(4x+1). (x-5)
4x+1=0 4x= -1 x= -1/4
x-5=0 x= 5
It grows by 10% each year. multiply the number by 0.1, then add. so 0.1×2420 is 242. add 242+2420=2662.
short answer:
this years tuition is $2662.
next years tuition is $2928.
'Tis a Binomial. if it were a monomial, there would be no operator between 6x^2 and 2xy^2
100-21=79
2859(0.79)^3=1409.598
worth $1409.60
and surely you'd know what the roots are
