2x2 + 15x + 25 = (2x + 5)(x + 5)
2x2 + 21x + 49= 2x2 + 14x + 7x + 49= 2x(x + 7) + 7(x + 7)= (x + 7)(2x + 7)
2x2+9x+9 = (2x+3)(x+3) when factored
Presumably all the terms are positive? (2x+7(x+7)
If you mean: 2x2+15x+25 then it is (2x+5)(x+5)
2x2+21x+49 = (2x+7)(x+7)
(2x+7)(x+7)
2x2 + 15x + 25 = (2x + 5)(x + 5)
2x2 + 21x + 49= 2x2 + 14x + 7x + 49= 2x(x + 7) + 7(x + 7)= (x + 7)(2x + 7)
2x2 + 21x + 49 = (2x + 7)(x + 7)
