It is: 12^2 = 144
The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.
(-4)^2 - ( - 2)^2 = Factor ((-4) + (-2))((-4) - (-2)) = (-4 -2)(-4 + 2) = (-6)(-2) = (+12) Or more simply 16 - 4 = (+12)
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
b = sqrt32 or 4 root 2
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
It is: 12^2 = 144
12 Squared = 12 * 12 = 144
The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.
4 squared minus 2 squared equals 12
(-4)^2 - ( - 2)^2 = Factor ((-4) + (-2))((-4) - (-2)) = (-4 -2)(-4 + 2) = (-6)(-2) = (+12) Or more simply 16 - 4 = (+12)
-22 - 12 = -8
Answer : 12
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
b = sqrt32 or 4 root 2
12
I think you're asking what multiplying a number by itself is called. If so, it's called "squaring" or "squared". For example: 2 squared, (or 2 x 2) which is 22 = 4 5 squared, (or 5 x 5) which is 52 = 25 12 squared, (or 12 x 12) which is 122 = 144
