x equals quantity of negative 7 plus or minus I square root of 6 all over 2

x equals quantity of negative 7 plus or minus I square root of 3 all over 2

x equals quantity of 7 plus or minus I square root of 6 all over 2

x equals quantity of 7 plus or minus I square root of 3 all over 2

Answer 1

\(\large\color{blue}{ \rm x^2 - 7x = -13}\)
\(\large\color{blue}{ \rm x^2 - 7x +13=0}\)

\(\LARGE\color{blue}{ \rm \frac{-(-7)±\sqrt{(-7)^2-4(1)(13)} }{2(1)} }\)

\(\LARGE\color{blue}{ \rm \frac{7±\sqrt{49-52} }{2}}\)

\(\LARGE\color{blue}{ \rm \frac{7±\sqrt{-3} }{2}}\)

Answer 2
