Question

Answer 1

c: \(\dfrac{15x^3y^3-10x^2y^3+25x^2y^2}{5x^2y^2}=3xy-2y+5\)

d: \(\dfrac{-8x^7y^2+12x^4y-4x^3y}{8x^3y}=-x^7y+\dfrac{3}{2}x-\dfrac{1}{2}\)

Answer 2

(-7x⁶ + 21x⁴ - 14x³) : \(\dfrac{7}{2}x^2\)

= \(-7x^6:\dfrac{7}{2}x^2+21x^4:\dfrac{7}{2}x^2-14x^3:\dfrac{7}{2}x^2\)

= -2x⁴ + 6x² - 4x
