Answer:

No, it is 3x-5 and r=0

Step-by-step explanation:

We can do it by long division method  the required quotient is 3x-5 and r=0

not 3x-1 , r=1

multiply the divisor with 3x  we will get \(3x^2+9x\)to cancel out the first term of dividend

Now after solving we will get \(-5x-15\)

Now, multiply the divisor by -5 we will get -5x-15 which will cancel the entire dividend.
