you do (245x)
-5
2y2(3y - 1)
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
2a2b2+3a2b2-5abc
you do (245x)
-5
5(3-2x)
-5
-5
(x-7)(x-3)
It is 2(2x+3) when factorised
x^2 - 10 x + 25 = (x - 5)(x - 5)
8x2 - 10x - 3 = (2x - 3)(4x + 1)
The magnification of a microscope is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece. In this case, if you have a 10x low power objective and a 10x high power objective, the total magnification would be 100x (10x * 10x) for both objectives when used with the same eyepiece magnification.
10x magnification means that an object appears 10 times larger than its actual size, while 40x magnification means that the object appears 40 times larger than its actual size. These magnifications are commonly used in microscopes to view objects in greater detail.
