Iam almost done with this write (4x + 3)2 in expanded form using the polynomial identity (x + y)2 = x2 + 2xy + y2. a.) (4x + 3)2 = (4x)2 + 2(x)(3) + (3)2 = 16x2 + 6x + 4 + 3)2 = (4x)2 + 2(4x)(3) + (3)2 = 16x2 + 24x + 9 c.) (4x + 3)2 = (4x)2 + (4x)(3) + (3)2 = 16x2 + 12x + 9 d.) (4x + 3)2 = (16x2 + 9)

Hello from MrBillDoesMath!

Remark:   It is customary to use x^2,  not x2, to indicate the square of x.

Discussion:

(4x + 3) ^ 2=   ( 4x)^2 + 2 * (4x)(3) + 3^2 =

                       16 x^2 + 24x  + 9

Thank you,

MrB

5 x 14?

im new, sorry if this is wrong.
