$\begin{matrix}\left(-3\right)\left(4\right)=-12\\ \left(-3\right)+\left(4\right)=1\end{matrix}$
Learn how to solve differential calculus problems step by step online. Solve the rational equation 1/(x^2+x+-12)+-2/(x^2-16)=0. Factor the trinomial x^2+x-12 finding two numbers that multiply to form -12 and added form 1. Thus. Factor the difference of squares x^2-16 as the product of two conjugated binomials. The least common multiple (LCM) of a sum of algebraic fractions consists of the product of the common factors with the greatest exponent, and the uncommon factors.
