Factoring a problem twice

The video tutorial emphasizes the importance of practice and repetition in learning. It introduces basic and advanced factoring techniques, starting with finding the greatest common factor (GCF) and moving to more complex examples. The instructor suggests a method of covering solved problems and attempting them independently to enhance understanding. The tutorial aims to build confidence in solving mathematical problems through consistent practice.

What is the recommended method to practice solving problems according to the video?

• Cover the solution and attempt the problem independently.

• Read the solution and memorize it.

• Ask a friend for the solution.

• Skip the problem if it's too hard.

What is the first step in factoring an algebraic expression?

• Add all the terms together.

• Multiply all the terms.

• Look for the greatest common factor (GCF).

• Divide by the smallest number.

When factoring the expression 3x(x^2 - 2x - 15), what is the GCF?

• x^2

• 15

• 3x

• 2x

What should you do if you see an opportunity to factor an expression further?

• Factor it further.

• Divide by the highest coefficient.

• Ignore it and move on.

• Multiply the terms again.

Which pair of numbers multiplies to -15 and adds to -2 in the expression x^2 - 2x - 15?

• -3 and 5

• 5 and 3

• -5 and 3

• 15 and -1
