19x
x^2-19x+90 (x-9) (x-10)
x=-2
6x2+19x+10 = (2x+5)(3x+2) Length = 2x+5 Width = 3x+2
(x+7)(x+12)
8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2
19x+1x+37=0 First add the 19x and 1x together 20x+37=0 Next subtract 37 to the other side 20x=-37 Now divide both sides by 20 x=-20/37
no one can do that. it doesn't make scence
(3x + 1)(x + 6)
(x - 10)(x - 9)
(x + 12)(x + 7)
Factor as : (x+9)(x+10) using the first terms ( x terms) multiply to x2; the last terms multiply to 90; the sum of 9x + 10 x = 19x
