Answer:
19+6x
Step-by-step explanation:
2×2+x+5x+15
4+6x+15
19+6x
Not sure about remainder theorem but I'm sure that the last terms should all multiply tho the last term
see the expanded form is -45
so the last terms of each binomial should multiply to -45
3 times -5 times ?=-45
-15 times ?=-45
divide by -15
?=3
the question mark is 3
