sqrt(4x2) = ± 2x
In real numbers there is no square root of -4x2 However, when using complex numbers where √-1 = i, then: √-4x2 = 2xi If you were asking, for example, with regard to the difference of two squares, eg y2 - 4x2, then you are actually finding the square root of 4x2 which is 2x, giving: y2 - 4x2 = (y + 2x)(y - 2x)
4x2 - 2x = 0

4x2 timber is commonly used in construction projects for framing, such as for walls, floors, and roofs. It is also suitable for building shelves, furniture, and other structural elements. Its versatility and strength make it a popular choice for various construction applications.

Accuracy describes how close measurements are to the actual value. It is a measure of how well the results agree with the true value of the quantity being measured.
Solid timber is what you'd expect it to be - actual wood. When people say 'solid timber' they want to let you know that the piece of furniture is not made from veneered particle board/mdf etc which may look like solid timber to the untrained eye.
The name for the ratio of a diagram measurement to actual measurements is the scale.

12x * 4x2 = 48x3
(x3 + 4x2 - 3x - 12)/(x2 - 3) = x + 4(multiply x2 - 3 by x, and subtract the product from the dividend)1. x(x2 - 3) = x3 - 3x = x3 + 0x2 - 3x2. (x3 + 4x2 - 3x - 12) - (x3 + 0x2 - 3x) = x3 + 4x2 - 3x - 12 - x3 + 3x = 4x2 - 12(multiply x2 - 3 by 4, and subtract the product from 4x2 - 12)1. 4x(x - 3) = 4x2 - 12 = 4x2 - 122. (4x2 - 12) - (4x2 - 12) = 4x2 - 12 - 4x2 + 12 = 0(remainder)
4x2 + x2 = 8 + x2
4x2 - 9y Not factorable from what I see.
