(2x-5) (x-1)
Sqrt(24x4)/Sqrt(3x) = Sqrt(24x4/3x) = Sqrt(8x3) = Sqrt(4x2*2x) = 2x*sqrt(2x)
4(2x+3) [there's 4 equal sides] 4(2x)+4(3) 8x+12

It is: (2x-5)(2x-5) = 2.5 square cm when solved as a quadratic equation
If you are adding,it would be 4x,but if you were multiplying,it would be 4x square

there is no problem with this quadratic equation it's 2x square - 3x -2 = 0 I need an answer. where it says square there should be a little 2 at the top corner of the 2x to make it 2x square thanks If you can't factor it easily then use the quadratic equation: The two solutions are: 2 & -.5
(2x-5) (x-1)
Sqrt(24x4)/Sqrt(3x) = Sqrt(24x4/3x) = Sqrt(8x3) = Sqrt(4x2*2x) = 2x*sqrt(2x)
4(2x+3) [there's 4 equal sides] 4(2x)+4(3) 8x+12
The area is 4x2 square units
2x*r2 square units where r is the radius and 2x is the angle (measured in radians).
Each side of the square is 2x+1.5 and its area is (2x+1.5) squared
