simplify : (x+9) ( x+ 17) ( 2x+3) (2x-5)​

Answer 1

Question:

Simplify:

            (x+9) ( x+ 17) ( 2x+3) (2x-5)​

Answer:

             4x^4+108x^3+597x^2-1002x-2295

Step-by-step explanation:

=[(x+9)*( x+ 17)]*[( 2x+3)*(2x-5)​]

[(x+9)*( x+ 17)]= x*x+x+17+9*x+9*17

                     = x^2+17x+9x+153

                     = x^2+26x+153

[( 2x+3)*(2x-5)​]= 2x*2x-2x*5+3*2x-3*5

                       = 4x^2-10x+6x-15

                       =4x^2-4x-15

So now...

              = (x^2+26x+153)*(4x^2-4x-15)

              = 4x^4+4x^3-15x^2+104x^3-390x+612x^2-612x-2,295

              = 4x^4+108x^3+597x^2-1002x-2295
