Work Step by Step

Distribute the parentheses $x^{2}+4x+12=0$ Factor the LHS For $x^{2}+bx+c$ we search for two factors of c, such that their sum is b... For c=12, no two such factors exist (with a sum of 4). The LHS can not be factored, and the equation has no real solutions. Solution set: $\emptyset$
