Solving Equations with the Distributive Property

Missed the previous lesson?

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

THIS GUY DOES EVERYTHING SO Differently!!

[potatonado]

I had to go solve one of these in front of the class and this saved me. My teacher doesn’t explain anything. She tells us what we need to do but she doesn’t explain why and how we are doing it and what it does.

I paused the video straight away and tried to solve, but that invisible 1 really fucked me up at the start bro.

[raffiboiballs]

I actually wish this guy was my teacher tbh, thanks my man
i got an a+ on my math exam cause of this!

I always struggled with the Distributive Property. Appreciated.

[sinistersmallblock]

Once he added the 1 to replace the 9 I got confused. Why is it a -1 instead of -9 x -9X? Why does the 1 replace the 9??

Please Help Me :''''( I Don't Under Stand a

Very useful video, except I, can imagine that younger viewers could be confused by -1(9x-6) You can simplify this expression by multiplying by 1, not -1.

[wadewilson]

What about distribution property with exponents

[iamthestrongest]

I don't have any words.. Thank you so much khan academy because of you this just became soo easy. it doesn't matter how hard anything is I just come and search whatever i want to learn by khan academy then boom next minute i am master at it. thank you soo much

[magnificentpanda]

-9 is the smallest you would have to subtract it on both sides.. That’s how I was thought and will it work also?

[silverspoon]

Thank you so much for your help !
Loved it the vid

[matttheawesome]

im so confused buy the invisible -1 what is its purpose, why do we put it there? why not just minus -9 from the first expression?

[giovannilopez]

What is the hidden number when there is a negative sign in front of parentheses

[annatilles]

why did you add that 1 up there? i dont get that

[Smoove]

Omfgggg why can't I understand math it takes me way slower to comprehend math then other people I just don't know also don't know how I got straight B's😂

[akshobhyamanthati]

he always does the easy questions and not the hard ones

[corsinchristoffel]

math is a science without it no other science could exist
