Please explain how to get the equation when its equal to 200

Suppose a unit of capital costs $2 and a unit of labour costs $4. The production
function is Q = 6KL + 2L².
(a) Using Lagrange multipliers calculate the maximum possible output Q when the total
input cost is $200.
(b) Measuring labour (L) on X-axis and capital (K) on Y-axis, show the optimal level of L and
K in a diagram.
