Simplify the following expression. classify the resulting polynomial.
4x(x+1)-(3x-8)(x+4)

x^2+32,quadratic binomial

Step-by-step explanation:

4x(x+1)-(3x-8)(x+4)

=4x^2+4x-(3x^2+12x-8x-32)

4x^2+4x-3x^2-4x+32

x^2+32

It has two terms,therefore it is quadratic binomial.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
