2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
49 plus 10 equals 59.
49 plus 7 equals 56.

i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
Remember in algebra any operation you do to one side of the equaution and also to the other side does not affect the eqaution 8x + 7 = 2x + 49 subtract 2x from both sides 6x + 7 = 49 subtract 7 from both sides 6x = 42 divide both sides by 6 x = 7
49 plus 10 equals 59.
49 plus 7 equals 56.

2x2 + 21x + 49 = 2x2 +14x +7x + 49 = 2x(x + 7) + 7(x + 7) = (2x + 7)(x + 7)
2x2+21x+49 = (2x+7)(x+7)
-x2+14x=49
2x2 + 21x + 49= 2x2 + 14x + 7x + 49= 2x(x + 7) + 7(x + 7)= (x + 7)(2x + 7)
49 + 72 + 68 = 189
