x = square root of 3.
I'm assuming that "x" is a variable. In this case isolate the x. (2*2)/9 = x. You would get, x = 0.44~
What is the solution set of 2x2 + x = 15
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7
I'm assuming the question is: 2x2 = 24x x = 0 or x = 12
The answer is x=0
If: 2x2 = 4 Then: x = the square root of 2
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
x = 2.1374586088176875 x = -1.6374586088176875
2x2-x-3 = 0= 4 - x - 3 = 0= 1 - x = 0= 1 = xTherefore x = 1
2x2 - 3 = 13 So 2x2 = 16 x2 = 8 So that x = ±2√2
4 x 25 = 100 The real answer is 104.
The product of the roots of the equation 2x2 -x -2 = 2 is 2x2 -x -2 = 2.
