Split screen. The left is a white background with a math word problem written in blue. The prompt reads, "Determine if the situation represents an inverse variation." To the right, a woman works through the problem using a screen in front of her. Caption. We want to determine if this is an inverse variation situation.

Aerial side view of a left hand touching a computer screen displaying a partially visible math problem written in blue. Caption. After you've factored your numerator, it's smooth sailing.

Split screen. The left is a white background with blue text that reads, "Example 2. Evaluate 3 minus 10, X, when X equals 2 over 5." Handwriting below reads, 3 minus 10 times 2 over 5. To the right, a woman works through the problem using a screen in front of her.

Aerial side view of a hand touching a computer screen displaying a math problem written and worked out in long form in blue. The problem at the top reads, "How did I get that?" Caption. And I know there's going to be a plus sign in between."

Split screen. The left is a white background with blue text that reads, "Example 4, factor completely. 4x squared minus X minus 3." To the right, a woman works through the problem using a screen in front of her.

Split screen. The left is a white background with blue text that reads, "Example 5, factor completely," above a handwritten polynomial equation in the midst being solved. a woman works through the problem using a screen in front of her.

Split screen. The left is a white background with an algebra equation being worked out in long form in blue. Given F, X equals 6, X minus 4, Find F, 1. To the right, a woman works through the problem using a screen in front of her.

Aerial side view of a computer screen displaying a math problem written and worked out in long form in blue. The problem at the top reads, "How did I get that?" Caption. When negative 2 is my input, 12 is my output.

Split screen. The left is a white background with an algebra equation is being worked out in long form in blue. To the right, a woman works through the problem using a screen in front of her.

Aerial side view of a computer screen displaying a math problem written and worked out in long form in blue. The problem at the top reads, "Example 1. Find the zeros of the quadratic function." Caption. I'll set both parts equal to 0, individually.
