2x2 + 21x + 49 = 2x2 +14x +7x + 49 = 2x(x + 7) + 7(x + 7) = (2x + 7)(x + 7)
2x2 + 21x + 49= 2x2 + 14x + 7x + 49= 2x(x + 7) + 7(x + 7)= (x + 7)(2x + 7)
196 98x2=196 49x2=98 7x7=49 2x2&7x7
x2+14x+49 = (x+7)(x+7) when factored
Yes.
2x2+21x+49 = (2x+7)(x+7)
2x2 + 21x + 49 = 2x2 +14x +7x + 49 = 2x(x + 7) + 7(x + 7) = (2x + 7)(x + 7)
(2x+7)(x+7)
2x2 + 21x + 49= 2x2 + 14x + 7x + 49= 2x(x + 7) + 7(x + 7)= (x + 7)(2x + 7)
2x2 + 21x + 49 = (2x + 7)(x + 7)
7(5x + 9y)
2x^2 - 21x + c = 0 x^2 - 21x/2 + c/2 = 0 (x + a)(x + 2a)= x^2 - 21x/2 + c/2 x^2 + 3a + 2a^2 3a = -21/2 ------> a = -7/2 2a^2 = c/2 ---> 49/2 = c/2 ---> c = 49
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form

x2+14x+49 = (x+7)(x+7) when factored
Yes.
