a)
Starting with 3^2y^2dy/dx=2−1,
We can simplify it to 9y^2dy/dx=1.
Now, we can separate variables:
9y^2dy=dx
Integrating both sides:
∫9y^2dy=∫dx
9/3y^3=x+C1
3y^3=x+C1
Solving for y:
y=(x+C1/3)^1/3
So, the general solution for equation (a) is:
y=(x+C1/3)^1/3
b)
For the second equation 2dy/dx+3=−2−5,
let's isolate dy/dx :
2dy/dx=−2−5−3
2dy/dx=−10
Now, divide by 2:
dy/dx =−5
This is a first-order linear differential equation, so its solution is straightforward. Integrating both sides:
∫dy=∫−5dx
y=−5x+C2
So, the general solution for equation (b) is:
y=−5x+C2
Hope this helps!
