Question

How do you solve the quadratic using the quadratic formula given `2t^2+15=6t^2-5t` over the set of complex numbers?

Answer 1

`t=(10+-sqrt265)/8`
There are no complex results because the graph passes through the x axis.

Explanation:

`2t^2+15=6t^2-5t`
`15=4t^2-5t`
`0=4t^2-5t-15`
`t=(10+-sqrt(25-(4*4*-15)))/(2*4)`
`t=(10+-sqrt265)/8`
