Which polynomial is in standard form?
9+2x–8x*+16x5
1289 – 6x2–9x+12
13x5 + 11x-6x2+5
7x? + 14x® – 17x+25

2x3 + 4x2 - 6) - (x2 + 5)(x2 + 6)

17x4 + 36x3 - 11x2 - 54x - 30. i think this is right

Step-by-step explanation:

is it 35

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
