reset counter in tasks environment

Question

Can someone please help me reset the counter(?) in the code below. The Answer section should start with #1. I do need

\RenewTasks[resume, style=custom,label-align=right]{tasks}(2)

in the preamble.

Thank you.

\documentclass{book}
\usepackage[a4paper, top=2cm, bottom=2cm]{geometry}
\usepackage{multicol, paralist, multirow, amsmath, amsthm, amssymb, amsfonts, ulem}
\usepackage{tasks}[2014/07/20]

\DeclareInstance{tasks}{custom}{default}{
  counter-format  = tsk. ,
  label-format    =  \bfseries ,
  label-width     = 2em ,
  label-offset    = .3333em ,
  after-item-skip = 5pt
}
\RenewTasks[resume, style=custom,label-align=right]{tasks}(2)

\begin{document}

In Exercises 1-8, factor the common factor in the polynomials. 
\begin{tasks}(3)

$4x^3 + 10x^2 - 2x$
\end{tasks}

\begin{tasks}(1)
\task
This is a long word problem, more than one line. I can't seem to use rlap for this. I have to use another begin{tasks} section here. 
\end{tasks}

In Exercises 8-13, solve the polynomial equations. 
\begin{tasks}(2)
\task
$x(x+12) = 0$
\task
$(2x+1)(2x-1) = 0$
\end{tasks}

Welcome to TeX.SX! Please add your code in the question window, not as a screen shot. The counter is probably called task, so a \setcounter{task}{0} before the answers start should do, but I have never used this package at all — , Sep 28 '14 at 05:02
Hi Christian. Thanks for the reply. I tried that but it didn't work. — Sean N, Sep 28 '14 at 08:07
Sean N, I wrote a short message to the maintainer of task, he is also a user here (cgnieder!) — , Sep 28 '14 at 09:10

Two things:

To accomodate a long item, you don't need to start a new environment. Just use \task*

\task*
This is a long word problem, more than one line. I can't seem to use rlap for this. I have to use another begin{tasks} section here.

Second, you can pass the option [resume=false] locally, when you type answers

\begin{tasks}[resume=false](2)

As an aside, instead of hard coding question ranges, you can label the questions and use \ref

As an alternative, you may define these:

\NewTasks[resume, style=custom,label-align=right]{questions}(2)
\NewTasks[style=custom,label-align=right]{answers}

and use them like

\begin{questions}(3)
\task
$3x^3 - 21x$
\end{questions}

\begin{answers}(2)
\task
$3x^3 - 21x$
\end{answers}

so that code is more readable. You may change the separator \task too, if you wish. For details refer to the manual.
