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
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
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
To divide the polynomial (14x^3 - 45x^2 - 28x - 4) by (7x + 2), we can use polynomial long division. Performing the division yields a quotient of (2x^2 - 9x - 2) with a remainder of (-18). So, the result is (2x^2 - 9x - 2 - \frac{18}{7x + 2}).
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

(7x + 4)(49x^2 - 28x + 16)
X squared + 7X + 12?
