2x2 + 21x + 49 = (2x + 7)(x + 7)
2x2+21x+49 = (2x+7)(x+7)
(2x+7)(x+7)
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
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)
(2x+3)/(10x2+21x+9)Factor the quadratic expression in the denominator:(2x+3)/(5x+3)(2x+3)which becomes:1/(5x+3) or (5x+3)-1
(2x - 1)(x - 10)
10x2 + 21x - 10 = 10x2 + 25x - 4x - 10 = 5x(2x + 5) - 2(2x + 5) = (2x + 5)(5x -2)
It is 6x(2x+5) when factored
10 + 2(x - 1) + 7 x 3x + 1 =10 + 2x - 2 + (7 x 3x) + 1 =10 + 2x - 2 + 21x + 1 =2x + 21x + 10 - 2 + 1 =23x + 9
4x2 + 12x + 5 = (2x + 1)(2x + 5).
-x2 + 2x + 48 = (x +6)(8 - x)
