X= plus or minus 8/ 1 1.

2, -25(2X- 1) squared =-4 (2X- 1) squared =-4/-25.

2X- 1= plus or minus 2/5 X=7/ 10 X=3/ 10.

3. The square of (3x-1) = the square of (1-4X) 3X- 1= plus or minus (1-4x).

So X=2/7 or X=0.

1. square root x =12. Square root 2-X X+ 1 3. Square root 2-3X+ square root x+1.

4. Square root -x square 5.9X square-1=0 6. The square of (2X+ 1) -36=0.

Square root A +2ab+b = positive or negative (a+b)

Substitute the following conditions: plus or minus 5 plus or minus 5/6 0 plus or minus 1.

The square root 2a- 1+ square root b+ 1\4=0 is known to find the value of a b.

It is known that the square root x=2y-5+|2x-y-5|=0.

(1) Find the values of x and y (2) Find the square root of (x+y)
