x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
the answer to 8 x 5 is 40
1*40 2*20 5*8
1 x 40 = 40 2 x 20 = 40 4 x 10 = 40 5 x 8 = 40
40/2 x 5 = 20 x 5 = 100
-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)
40 = 5(x-10) 40 = 5x - 50 5x = 40 + 50 x = 90 / 5 x = 18 to check : 40 = (?) 5 (18 - 10) 40 = 5 (8) 40 = 40
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
1, 2, 4, 5, 8, 10, 20, 40: 1 x 40, 2 x 20, 4 x 10, 5 x 8Also, 2 x 2 x 2 x 5 = 40
5/8 x 40 = 25
