-16
(13x)2 = 169x2
13x-14 or 13x+(-14)
2x2 - 13x - 7 = (2x + 1)(x - 7)
13x 32 plus 5x can be expressed mathematically as 173x/32.
(8x2)-(13x-16)= -78
7 + 13x = -9 ie 13x = -9 - 7 x = -16/13 or "Minus one and three thirteenths"
(x - 16)(x + 3)
x=-16 , y= -31/3
13x
-16
13X squared + 7X + 12
13x - 4x = 9
13x-10x = 3
(13x)2 = 169x2
-x^2 -13x -40 = -(x^2 + 13x + 40) = -(x + 5)*(x + 8)-x^2 -13x -40 = -(x^2 + 13x + 40) = -(x + 5)*(x + 8)-x^2 -13x -40 = -(x^2 + 13x + 40) = -(x + 5)*(x + 8)-x^2 -13x -40 = -(x^2 + 13x + 40) = -(x + 5)*(x + 8)
13x-14 or 13x+(-14)
