B^2 + 8b + 16 factoring polynomials with a leading coefficient

  (b +4)²

Step-by-step explanation:

Here, you recognize the constant as the square of half the coefficient of the linear term: 16 = (8/2)². This means the trinomial is a perfect square, so can be factored accordingly.

  b² +8b +16 = (b +4)²

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
