You asked:

Investigate the equation: \(4 {\cos\left( 60 \right)}^{2} = 3 - 4 \cos\left( 60 \right)\).

MathBot Answer:

This equation has no unknown quantities, so it is either true or false.

This equation is false because the left-hand side is not equal to the right-hand side.

The left-hand side of the equation is:

\[4 {\cos\left( 60 \right)}^{2} = 4 \cos^{2}{\left(60 \right)}\]

The right-hand side of the equation is:

\[3 - 4 \cos\left( 60 \right) = 3 - 4 \cos{\left(60 \right)}\]
