Factorise : (viii) 5x^(2) - (20x^4)/( 9)

If (x ^(2) +x+1) + (x^(2) + 2x +3) + (x^(2) + 3x +5) + ….. + (x ^(2) + 20x + 39) =4500, then x is equal to :

If (x ^(2) +x+1) + (x^(2) + 2x +3) + (x^(2) + 3x +5) + ….. + (x ^(2) + 20x + 39) =4500, then x is equal to :

The remainder obtained when 80x^(3) + 55x^(2) + 20x + 172 is divided by x +2 is _____

Do the following divisions.(i) -20x^(4)-:10x^(2) (ii) 7x^(2)y^(2)z^(2)-:14xyz

factorize : x^2+20x-69

f(x)=10x^(2)-20x+5

Factorise: x ^(2) - 20x+ 100

10x^(2)-20x+1=0
