Question

Answer 1

b) \(\left(6x^2+\dfrac{1}{3}\right)^2=36x^4+4x^2+\dfrac{1}{9}\)

c) \(\left(5x-4y\right)^2=25x^2-40xy+16y^2\)

Answer 2

b. \(\left(6x^2+\dfrac{1}{3}\right)^2=36x^4+4x^2+\dfrac{1}{9}=\left(6x^2\right)^2+\left(2x\right)^2+\dfrac{1}{9}\)

c. \(\left(5x-4y\right)^2=25x^2-40xy+16y^2\)
