28x2 / 7x2 = 4
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1

4x2+28x+49 = (2x+7)(2x+7) when factored
I assume that is (7x-2)^2 = 16 (7x-2)(7x-2) = 16 49x2 -28x +4 = 16 49x2-28x-12=0 use quadratic formula x = ( -b +/-sqrt(b2-4ac) ) /2a x = -2/7
7x+7=28x 28x-7x=7 21x=7 x=3
49x2+28x+4 = (7x+2)(7x+2) when factored
3.5
7x + 8
The area of square is : 49.0
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
