When factored it is: (x+9)(x-1)
x2 + 8x - 20 = (x - 2)(x + 10).
x2 + 8x - 9 = (x + 9)(x - 1)
(x - 3)(x - 5)
(x + 9)(x - 1)
X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16
Answer is x2 -6x+14 with remainder 2
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
(x + 9)(x - 1)
x2 + 8x = x(x+8)
x2-9x+8=0 has two solutions:x = 8x = 1
Yes, both brackets will contain a minus sign. (x -2)(x-6)
