What is the square root of four x squared?
The square root of 4x^2 is solved by first doing the square root of 4. This is plus or minus two - because -2 x -2=4. The square root of x^2 is x. So the answers are 2x or -2x. If your question was (4x)^2, then the answer would be 4x.
How do you factor x squared plus x minus one half?
(x^2+x-1/2)= x(x+1)-1/2 [x + (1 - square root of 3)/2][x + (1 + square root of 3)/2] = 0 Check it: x^2 + x/2 + (square root of 3)x)/2 + x/2 + 1/4 + (square root of 3)/4 - (square root of 3)x/2 - (square root of 3)/4 - 3/4 = 0 x^2 + x/2 + x/2 + [(square root of 3)x]/2 - [(square root of 3)x]/2 + (square root of 3)/4 - (square root of 3)/4 + 1/4 - 3/4 = 0 x^2 + x - 2/4 = 0 x^2 + x - 1/2 = 0 How to find this roots: Using the completing the square method: x^2 + x - 1/2 = 0 x^2 + x = 1/2 x^2 + x + 1/4 = 1/2 + 1/4 (x + 1/2)^2 = 3/4 x + 1/2 = (plus & minus)(square root of 3/4) x = -1/2 + (square root of 3)/2 x = - 1/2 - (square root of 3)/2

Can you rationalize the denominator using conjugates even when the denominator contains two radical terms?
Yes. For example, the conjugate of (square root of 2 + square root of 3) is (square root of 2 - square root of 3).
What is 3 root 2 minus root 2?
Oh, what a happy little math problem we have here! When you have 3 times the square root of 2 minus 1 times the square root of 2, you can combine like terms. So, 3 root 2 minus root 2 is equal to 2 times the square root of 2. Just like that, we've created a beautiful, simplified expression.
Can you solve x squared minus 4x minus 2 equals 0?
