Difference of Squares

[anastufan]

Or you just solve the two brackets individually, since they’re equal to zero anyways. It’s nice to refresh your memory tho, so thank you!

Loving your videos! Keep 'em coming.

There is no need to all of that; since A*B=0 means that A=0 or B=0, just make each term equals 0.

[maxhenderson]

You also could have just set each bracket to zero and solved for each bracket separately i.e. x²-16 = 0, x²-10=0

Awesome as always! Thank you for posting your videos.

Multiplication can be seen from this type of product, in general, to correspond to a logical “or”. Addition would be a logical “anding” ooeration

[hardryv]

All fine & accurate of course, but given that one of the two starting terms had to equal 0, the 4 answers were fairly obvious without an assisting equation.

Please solve this.
Root under (5-x)=5-x².

Or you can just look at it and see that the answer is ±4, ±√10

You can calculate the sum of the squares all of the time, all of the squares some of the time, but you cannot calculate all of the squares all of the time.

Why did you replace -10 with square root of 10 squared????

[Kawomii]

why do we change the 10 to square root 10?

[VladiFx]

why sir? one of them must be zero! solution 1 and 2. thats all.

[nunopereira]

Hmmm not sure about this one chief...one of them must be equal to 0

[Mathe_schwer]

Why don’t we just say x^2-16=0 then x=+- 4 or x^2=10 then x=+-radical 10 ??
