Summary: We consider the boundary-value problem $-(\varphi_p (u'))' =\lambda f(u)$ in (0,1) $u(0) = u(1) =0$ where p> 1, $\lambda$ and $\varphi_p (x) =| x|^{p-2}x$. The nonlinearity $f$ is cubic-like with three distinct roots 0=a b c. By means of a quadrature method, we provide the exact number of solutions for all $\lambda$. This way we extend a recent result, for $p=2$, by Korman et al. [17] to the general case $p>1$. We shall prove that when $\1$p=$2 by Korman et al. [17], and strictly different in the case $p>2$.$
