Let's solve this equation.

Now we just solve the equation.

So let's just solve this equation.

It's a pretty easy equation to solve.

If they said, solve this equation, right?

And now we just solve the equation.

And now we just solve this equation.

Let's try to solve a more involved equation.

So how do we solve this differential equation?

So, this is how we solve Friedmann equation.

And then solve it as an exact equation.

But let's solve this properly as a differential equation.

Well, this is a pretty easy equation to solve

So now let's just solve this equation right there.

Let's solve another 2nd order linear homogeneous differential equation.

That's the best way to solve a quadratic equation.

Well, it's a way to solve a quadratic equation.

So you could use the quadratic equation to solve this.

So essentially they just want us to solve this equation.

They just want us to solve this equation right here, solve for I, so let's do that.

You actually need two initial conditions to solve this differential equation.

So this is essentially the equation and now we can solve it.

It's kind of a sub differential equation to solve our broader one.

It doesn't look like this is really an easy algebraic equation to solve.

And the way you want to solve this, this is a quadratic equation.

Now, to solve this, we just divide both sides of this equation by 3.

It's a differential equation. However, in order to solve it, we need something else.

if you remember actually from the earlier quiz in this, if you solve this equation.

We have the equation 16 (x 4) 2 and we need to solve for X.

So I have an equation I have one unknown, I can just solve for it.

But we can solve this without using the quadratic equation or without having to factor.

This problem is an equality of k so we first solve the assigned equation for k.

There, we just set up a equation with one unknown and we can solve for x.

So to solve for this we would just divide both sides of this equation by pi.

And now we can divide both sides of this equation by 0.15 to solve for x.

So if I rewrite the equation like this then now I can solve for my weight.

Now, to understand how you can manipulate this equation to solve it, let's see a thing

Using just your first year calculus derivative and integrating skills, you can solve a separable equation.

And then to solve for x, we can multiply both sides of this equation times negative 1.

We set up the equation, we just have to use our algebraic tools to solve for 'B'

Now, next time, we will actually try to solve Friedmann Equation and actually reach the cosmological models.

I guess a quadratic equation is actually what you're trying to solve, and what a lot of people call the quadratic equation is actually the quadratic formula.

And if we just solve this equation as it is, we're going to get a value for x.

later on when we solve the differential equation, so you don't have to worry about it too much.

Now if I want to solve for B, I just have to divide the whole equation by 3.
