Factor the polynomial.
4m4 + 36m3 + 96m2 + 80m

4m^4+36m^3+96m^2+80m

Divide by 4m

4m(m^3+9m^2+24m+20)

4m(m^3+9m^2+24m+20)

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
