Answer 1

Step-by-step explanation:

Can't explain all steps cause it is too long.

a) (3x+5y)^2

 = 9x^2+ 30xy + 25y^2        ( using (a+b)^2 = a^2+2ab + b^2 )

b) (17a-4) ^2

  = 289a^2 -136a + 16      (using (a-b)^2 = a^2 -2ab +b^2)

d) (11+8p)^2

   = 121 + 176p+64p^2      (using (a+b)^2  = a^2+2ab+b^2)

e) (p+q/3)(p-q/3)

   = p^2 - q^2/9                    (using (a+b)(a-b) = a^2-b^2)

g)  (7b-2a)^2

  = 49b^2-28ab+4a^2              (using (a-b)^2 = a^2-2ab+b^2)

h) (x+17)(x-17)

  = x^2 -289                              (using (a+b)(a-b) = a^2-b^2)

Hope it helps
