To factorise the expression (10x - 6z), first identify the greatest common factor (GCF) of the coefficients, which is 2. You can then factor out 2 from each term: (10x - 6z = 2(5x - 3z)). Thus, the factorised form is (2(5x - 3z)).
2y2(3y - 1)
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)

To factorise the expression (10x - 6z), first identify the greatest common factor (GCF) of the coefficients, which is 2. You can then factor out 2 from each term: (10x - 6z = 2(5x - 3z)). Thus, the factorised form is (2(5x - 3z)).
(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.
