Question

Nicole was solving the quadratic equation x²-6x+450 using the quadratic formula and

she obtained the following result: 6±√-144 2 x= Using what you have learned about complex numbers, rewrite the aboveresult as a complex number in simplified form a + bi

Answer 1

Explanation:

we have the values as

`(6 \pm √( - 144) )/(2)`

first, we note that

`√( - 144) = √( - 1) √(144) = 12i`

and so our solutions become

`(6 \pm 12i )/(2) = 3 \pm6i`
