2x squared minus 4
Your Problem: X - 4 = ?Current Problem: 3 [squared] - 4 = ?How: When a numbered is squared, it means you multiply it against itself. So, 3 squared equals 3x3.3x3 = 9So, you would then take 9 and minus it by 4, which would than equal 5.Answer:3 [squared] - 4 = 5or9 - 4 = 5
x2-4x-165 = (x-15)(x+11) when factored
-144
So u have the function x2-4=0 Now because 4 is a squared number, its square root is 2 (x+2)(x-2)=0
-4 - 112 = -4 - 121 = -125 (-4 - 11)2 = -152 = 225
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.
Factors of -8 are -1 & 8, -2 & 4, -4 & 2 and -8 & 1. Only -4 & 2 add to -2 so factors are (x + 2)(x - 4)
find the common multiple of 4 and 480 then minus 4. Answer is 1 over 3 and N squared. Your welcome i am your saviour.
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
