The line $ y\equal{}mx$ has 3 intersection points with the curve $ y\equal{}|x(x\minus{}1)|$. Find the value of $ m$ such that the area of the 2 regions bounded by the line and the curve are equal.
1. **Find the intersection points:**
   The line \( y = mx \) intersects the curve \( y = |x(x-1)| \). We need to solve for \( x \) in the equations:
   \[
   mx = x(x-1) \quad \text{and} \quad mx = -x(x-1)
   \]
   For \( mx = x(x-1) \):
   \[
   mx = x^2 - x \implies x^2 - (m+1)x = 0 \implies x(x - (m+1)) = 0
   \]
   Thus, \( x = 0 \) or \( x = m+1 \).

   For \( mx = -x(x-1) \):
   \[
   mx = -x^2 + x \implies x^2 + (m-1)x = 0 \implies x(x + (m-1)) = 0
   \]
   Thus, \( x = 0 \) or \( x = 1-m \).

   Therefore, the intersection points are \( x = 0 \), \( x = m+1 \), and \( x = 1-m \).

2. **Set up the integrals for the areas:**
   The area between the curve and the line from \( x = 0 \) to \( x = 1-m \) is:
   \[
   A_1 = \int_0^{1-m} \left[ x(1-x) - mx \right] \, dx
   \]
   Simplifying the integrand:
   \[
   A_1 = \int_0^{1-m} \left[ x - x^2 - mx \right] \, dx = \int_0^{1-m} \left[ (1-m)x - x^2 \right] \, dx
   \]

3. **Evaluate the integral \( A_1 \):**
   \[
   A_1 = \int_0^{1-m} (1-m)x \, dx - \int_0^{1-m} x^2 \, dx
   \]
   \[
   A_1 = \left[ \frac{(1-m)x^2}{2} \right]_0^{1-m} - \left[ \frac{x^3}{3} \right]_0^{1-m}
   \]
   \[
   A_1 = \frac{(1-m)(1-m)^2}{2} - \frac{(1-m)^3}{3}
   \]
   \[
   A_1 = \frac{(1-m)^3}{2} - \frac{(1-m)^3}{3} = \frac{(1-m)^3}{6}
   \]

4. **Set up the integrals for the second area \( A_2 \):**
   The area between the curve and the line from \( x = 1-m \) to \( x = 1 \) and from \( x = 1 \) to \( x = m+1 \) is:
   \[
   A_2 = \int_{1-m}^{1} \left[ mx - x(1-x) \right] \, dx + \int_{1}^{m+1} \left[ mx - x(x-1) \right] \, dx
   \]
   Simplifying the integrands:
   \[
   A_2 = \int_{1-m}^{1} \left[ mx - x + x^2 \right] \, dx + \int_{1}^{m+1} \left[ mx - x^2 + x \right] \, dx
   \]
   \[
   A_2 = \int_{1-m}^{1} \left[ (m-1)x + x^2 \right] \, dx + \int_{1}^{m+1} \left[ (m+1)x - x^2 \right] \, dx
   \]

5. **Evaluate the integrals for \( A_2 \):**
   \[
   A_2 = \left[ \frac{(m-1)x^2}{2} + \frac{x^3}{3} \right]_{1-m}^{1} + \left[ \frac{(m+1)x^2}{2} - \frac{x^3}{3} \right]_{1}^{m+1}
   \]
   \[
   A_2 = \left( \frac{(m-1)}{2} + \frac{1}{3} \right) - \left( \frac{(m-1)(1-m)^2}{2} + \frac{(1-m)^3}{3} \right) + \left( \frac{(m+1)(m+1)^2}{2} - \frac{(m+1)^3}{3} \right) - \left( \frac{(m+1)}{2} - \frac{1}{3} \right)
   \]
   Simplifying:
   \[
   A_2 = \frac{(m+1)^3}{6} + \frac{(1-m)^3}{6}
   \]

6. **Set the areas equal and solve for \( m \):**
   \[
   A_1 = A_2 \implies \frac{(1-m)^3}{6} = \frac{(m+1)^3 + (1-m)^3}{6}
   \]
   \[
   (1-m)^3 = (m+1)^3 + (1-m)^3
   \]
   \[
   0 = (m+1)^3
   \]
   \[
   m+1 = 0 \implies m = -1
   \]

The final answer is \( \boxed{ m = -1 } \)
