8x
The GCF is 8x.
If you mean: d = 56x+72y So if: 8 = 56x+72y Then: x = 1/14 and y = 1/18 Check: (56*1/14)+(72*1/18) = 8

The GCF is 8x.
16x2 - 56x + 49 = (4x - 7)2
Problem: -4-56x= 20. -56x=20+4. -56x/56=24/56. Answer: approx. .43
7X^2 -56X + 112 = 0 divide through by 7 X^2 - 8X + 16 = 0 factor (X-4)(X-4) X = 4
You didn't state what the problem is. Quite often you will want to either factor it, or solve the equation (in this case) 56x3 - 170x2 + 98x = 0. In this case, first take out the common factor "x". Then use the quadratic formula on what is left. (If, for example, 5 is a solution, then x - 5 is a factor.)
If that's + 21, the answer is (8x - 3)(8x2 - 7) If that's - 21, it gets ugly in a hurry.
The value of x in the equation 49x2 plus 56x plus 16 is -2.04.
35xy/56x let's split this into integers and variables to make it easier for you. 35/56 you factor out 7 from both numerator and denominator 7*5/7*8 you have the right to cancel any like factors both in the numerator and in the denominator ( factor mean something times something-not + or - ) so, the 7 is canceled; top and bottom 5/8 Now, same with variables xy/x x canceled; top and bottom y Now, that is how 35xy/56x can be 5y/8
49x2 - 56x + 16 = (7x - 4)2 so yes, it can be a perfect square.
-56x-4
It can only be simplified into: -56x-2
