" s."x^(2)+20x-69

factorize : x^2+20x-69

Factorise : 4x^2 + 20x - 96 .

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

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 :

If x = 10, then the value of (4x^(2) + 20x + 25) = ?

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