Question

what are the solutions of the equations x^2+14x=-130? (1point) a.2,-16 b.10,-13 c.-2,16 d.no solution

Answer 1

`x^2+14x=-130\\ x^2+14x+49=-81\\ (x+7)^2=-81`

no solutions in
`\mathbb{R}`

in
`\mathbb{C}`

`x+7=-√(-81) \vee x+7=√(-81)\\ x=-7-√(-81) \vee x=-7+√(-81)\\ x=-7-9i \vee x=-7+9i\\`
