I have a query related to completing square method lets say the question is
2x² + 3x + 2
and then 2x² + 3x + (3/2)² + 2 - (3/2)²

and what im doing is (2x + 3/2)² + 2 - 9/4

but im wondering as the identity is
(a+b)² = (a)² + 2(a)(b) + (b)²

so wouldn't that make it
((√2)x + 3/2)² + 2 - 9/4
as we are squaring the whole value of a in the identity

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2
