If there are 18 students every one of the will pair up with 17 other students throughout the year so the total amount of pairs that can be made is 18x17=306 but since it’s not important if student A is paired with student B or student B with student A we should divide the total amount of pairs by two- 306:2=153 so in total there will be 153 projects finished
Reember taht the antideritive of

is

antiderititive of 4x³=4(x^4)/4=x^4
antideritive of 3x²=3(x³)/3=x³
antiderititive of 6x=6(x²)/2=3x²
antideritiive of 5=5x
f(x)=x⁴+x³-3x²+5x+C
