Full solution

Q. Solve the differential equation.\newlinedydx=6xy\frac{dy}{dx}=6\sqrt{xy}
  1. Recognize type of differential equation: Recognize the type of differential equation.\newlineThis is a first-order differential equation that can be solved by separation of variables, where we separate the xx terms and yy terms on different sides of the equation.
  2. Separate the variables: Separate the variables.\newlineWe want to get all yy terms on one side and all xx terms on the other side. To do this, we divide both sides by y\sqrt{y} and multiply both sides by dxdx to get:\newlinedyy=6xdx\frac{dy}{\sqrt{y}} = 6\sqrt{x}dx
  3. Integrate both sides: Integrate both sides.\newlineWe integrate the left side with respect to yy and the right side with respect to xx:\newline(1/y)dy=6xdx\int(1/\sqrt{y})\,dy = \int 6\sqrt{x}\,dx
  4. Perform the integration: Perform the integration.\newlineThe integral of 1y\frac{1}{\sqrt{y}} with respect to yy is 2y2\sqrt{y}, and the integral of 6x6\sqrt{x} with respect to xx is 4x324x^{\frac{3}{2}}, so we have:\newline2y=4x32+C2\sqrt{y} = 4x^{\frac{3}{2}} + C, where CC is the constant of integration.
  5. Solve for y: Solve for y.\newlineTo solve for y, we square both sides to get rid of the square root:\newline(2y)2=(4x32+C)2(2\sqrt{y})^2 = (4x^{\frac{3}{2}} + C)^2\newliney = (2x32+C2)2(2x^{\frac{3}{2}} + \frac{C}{2})^2
  6. Check for math errors: Check for math errors.\newlineWe need to ensure that the squaring process was done correctly. Squaring the right side should distribute the square to both terms and the cross term:\newliney=4x3+2Cx32+(C2)2y = 4x^3 + 2\cdot C\cdot x^{\frac{3}{2}} + \left(\frac{C}{2}\right)^2
