Can we use the "discriminant way" for this...?
The curve y = (k-6)x^2 - 8x + k cuts the x-axis at two points and has a minimum point. Find the range of values of k.

I don't know of any such serious experiments that gave statistically significant results. Do you?

I have never observed banana seeds. Not even letting the bananas in the plant after they are ripe.
By experience I know that banana plants are multiplied by taking the newborn plantlets that multiply near the roots of the "mother" and planting them somewhere else. Banana plants fructify only once. They are usually cut after harvest. Then one of the "sons" takes the place of the removed one.
That is the case also for the "bread fruit" tree. No seeds in the fruit. Same procedure: "sons" are removed to multiply the plants.

int(r^3/sqrt(4+r^2))dr on the interval [0,1] using integration by parts

I've tried setting r^3=u =>du=3r^2 and setting dv=1/sqrt(4+r^2)
=>v=ln(r+sqrt(4+r^2))
This leads to the following:
int(r^3/sqrt(4+r^2))=(r^3)(ln(r+sqrt(4+r^2))) - int((3r^2)(ln(r+sqrt(4+r^2))))dr
This is the point I'm stuck at. Do I integrate by parts again? If so, what are my u and dv?
