25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
The expression is: 6-5x when simplified
5x plus 3 does equal 3 plus 5x; commutative law.
-10x + 5x = -5x
x=6
5x+5x-10 10x-10 is the only answer you can get from this
10x - 5x + 5x = 10x
It is: 5x
2x plus 5x simplified is 7x.
-5x^2 - 55x - 120
