Question

Step by step multiple

Answer 1

Answer:

hmmmmmmm so here is the answer:----

a). (2x+3y) (2x+3y)

=(2x+3y)^2

= (2x)^2 + 2×2x×3y + (3y)^2

((a+b)^2 = a^2 + 2ab + b^2 )

= 4x^2 + 12xy + 9y^2

b). (4p- 3q) (4p- 3q)

=(4p- 3q)^2

= (4p)^2 - 2×4p×3q + (3q)^2

((a+b)^2 = a^2 + 2ab + b^2 )

= 16p^2 - 24pq + 9q^2

c). (x+3) (x+9)

= x^2 +9x + 3x + 27

= x^2 + 12x +27

so mark it as brainlist if you are satisfied with the answer
