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.
2x squared minus 4
4 squared minus 2 squared equals 12
The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
- ln ((x^2)-4)
the square root of b squared minus 4 times a times c
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
negative 2 squared
The answer is 4, as 629 minus 4 equals 625. 625 is 25 squared.
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
It is: 9-4 = 5
4 squared is 16 The square root of 4 is 2 Hence, 4 squared is 14 greater than the square root of 4.
It is not clear what you want to solve for.
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
(x - 5)(x + 4)
Squared. E.g the square root of 4 is 2, and 2 squared is 4.
