( a2 ) ( a2+1 )
4 pieces of A4 fit on one piece of A2.
A4*2 = A3 A3*2 = A2 = 2*2*A4 A2*2 = A1 = 2*2*2*A4 = 8*A4 Answer: 8 pieces of A4 zized papers will fit on 1 sheet of A1.

Here a1 = -6, a2 = -1, a3 = 4 & a4 = 9 d = a2-a1 = -1-(-6) = -1+6 = 5 d = a3-a2 = 4-(-1) = 4+1 = 5 d = a4-a3 = 9-4 = 5 Therefore the common difference d = 5
(a^2 + 8b)(a^2 - 5b)
(a2+2b2-2ab)(a2+2b2+2ab)
While there are many ways of doing it, the simplest way is to use the SUM function and a range in it like this: =SUM(A1:A5)
Excel formulas that will find the average of cells A1, A2, and A4 are: =AVERAGE(A1 ,A2, A4) or =AVERAGE(A1:A2, A4)
an a2 has 6 pieces of a4
4 pieces of A4 fit on one piece of A2.
A2 is the biggest then A4 then A1
To make an A2 sheet, you need 4 A4 sheets. This is because A2 is twice the size of A3, which in turn is twice the size of A4. Therefore, combining four A4 sheets (2x2) will create the area of one A2 sheet.
Usually simple substitutions enable such expressions to be seen as quadratic expressions. The substitutions x = a2 and y = b2 give a4 + b4 - 7a2b2 = x2 - 7xy + y2 which does not have any rational factors. Consequently, the quartic in a and b does not have rational factors.

An A2 page measures 420 mm x 594 mm, while an A4 page measures 210 mm x 297 mm. Since A2 is four times the area of A4, you can fit four A4 pages onto one A2 page when arranged properly. This means two A4 pages can fit along the width and two along the height of the A2 page.
A4*2 = A3 A3*2 = A2 = 2*2*A4 A2*2 = A1 = 2*2*2*A4 = 8*A4 Answer: 8 pieces of A4 zized papers will fit on 1 sheet of A1.
