The area of a rectangle is 8x^2+14x+3. The length is 2x+3. What is the width?
Notice that 8x2 + 14x + 3 can be factored as (2x + 3)(4x + 1)
This should help.
.
A = 8x^2+14x+3
Notice that this factors as
(2x + 3)(4x + 1)
And since 2x + 3 is the length
Then, 4x + 1 must be the width .... since L x W = A
THX VERY MUCH!
