Do you know what a quadratic formula is?

x=

−b±√b2−4ac
2a
where the values of a, b, and c are substituted from the quadratic equation ax2 + bx + c = 0.

That looks hard.

It's not o hard. Let's try a problem. We will start with the following: First we want to write the equation in standard form and identify a, b, c

0=x^2+4x+1

This is in standard form.

a=1,b=4,c=1


x=

−b±√b2−4ac

2a


a = 1, b = 4, c = 1

x=

Compare the approximate solutions to the graph

The two approximate solutions are x = −0.27 and x = −3.73.

The x-intercepts are right where you expected them to be!

That's all there is to it. Was it as hard as you thought?

Not as hard as I thought but it is a lot of work with a lot of steps

I think you did just great and I am sure you are ready for the test.

Thanks. I think so too.

Compare the approximate solutions to the graph

The two approximate solutions are x = −0.27 and x = −3.73.

The x-intercepts are right where you expected them to be!

That's all there is to it. Was it as hard as you thought?

Not as hard as I thought but it is a lot of work with a lot of steps

I think you did just great and I am sure you are ready for the test.

Thanks. I think so too.

Do you know what a quadratic formula is?

x=

−b±√b2−4ac
2a
where the values of a, b, and c are substituted from the quadratic equation ax2 + bx + c = 0.

That looks hard.

It's not o hard. Let's try a problem. We will start with the following: First we want to write the equation in standard form and identify a, b, c

0=x^2+4x+1

This is in standard form.

a=1,b=4,c=1


x=

−b±√b2−4ac

2a


a = 1, b = 4, c = 1

x=

−(4)±√42−4(1)(1)

Substitute the values for a,b,c into the quadratic formula

Simplify using the order of operations
