The square root of -4 is: 2 i

9 square root 4 minus 12 square root 4 = -6

x plus the square root of 2

It is: (3*2)-(2*2) = 2

4 x square root of 10 minus square root of 10 = 3 x square root of 10.

?

(3 x 2) - (2 x 2) = 2

Minus square root of 2, minus square root of 3, minus pi, minus e, etc. Or, to be a bit more fancy, 1 - pi, 2 - pi, 3 - pi, pi - 4, pi - 5, 2 - e, e - 3, square root of 2 minus 2, etc.

2 x 2 = 4 -2 x -2 = 4

2

It is imaginary; we denote sqrt of -1 = i square root (-4) = ± 2i

the square root of 4 is 2 square root 2

4

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.

(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

3*sqrt(4) - 2*sqrt(4) = 1*sqrt(4) = 2

It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).

4 times 4 minus 4 minus square root of 4.

X2+5x-6. a=1, b=5, and c=-6 The formula is: -b plus or minus the square root of b squared minus 4ac all over 2a. -b+square root of b2-4ac ---- 2a -5 plus or minus the square root of 5 squared minus 4(1)(-6) -5 plus or minus the square root of 25-4(-6) -5 plus or minus the square root of 25+24 -5 plus or minus the square root of 49 -5 plus or minus 7 Here is where you split into two different answers: Number 1: -5 plus 7= 2 Number 2: -5 minus 7= -12 Your answer is X=2, -12

The Square-Root of 4 is 2 or -2.

In order to represent the square root of a minus number (which does not in fact actually exist other than as an abstract notion), mathematicians use an imaginary number called "i". i represents the value of the square root of -1. We must remember that it is not a real number, which is why we call it imaginary.So to answer your question, i, or a multiple of i, times itself equals a minus number.For example 2i * 2i = -4 (this is because we can rewrite -4 as 4 * -1. The square root of 4 is 2 and the square root of -1 is i. Therefore the square root of -4 is 2i).

2 is the same as the square root of 4. Square root of 4 multiplied by square root of 2 is equal to the square root of 8.

If x is a multiplication symbol, then square root of 36(4)y^2 = square root of(4^2)(2^2)(y^2) = (4)(2)(y) = 8y If it is a variable x, then square root of 36x4y^2 = square root of (4^2)(x)(2^2)(y^2) = (4)(2)(y)(square root of x)= 8y(square root of x)
