# Circles and Lines We just learned how to represent a circle with an equation. We've known for a long time how to represent a line with an equation. So let's use equations to examine what happens when circles and lines interact. We represent a generic circle with (xh)2 + (yk)2 = r2and a generic line with y = mx + b....
## Precalculus (6th Edition) Blitzer The standard form of the expression${{\left( 2-\sqrt{-3} \right)}^{2}}$ is $1-4i\sqrt{3}$. Consider the expression, ${{\left( 2-\sqrt{-3} \right)}^{2}}$ Rewrite ${{\left( 2-\sqrt{-3} \right)}^{2}}$ as ${{\left( 2-\sqrt{3}\sqrt{-1} \right)}^{2}}$ As $i=\sqrt{-1}$ Therefore, ${{\left...
