Simplify the expression<br> (4x-6y^(3))^(2)

Andru [333]

Answer:

16x^2 -48xy^3 +36y^6

Step-by-step explanation:

(4x-6y^(3))^(2)

FOIL

(4x-6y^3) (4x - 6y^3)

first: 4x*4x = 16x^2

outer : 4x (-6y^3) =-24xy^3

inner : 4x (-6y^3) =-24xy^3

last: -6y^3 * - 6y^3 = 36y^6

Add them together

16x^2 -24xy^3-24xy^3+36y^6

Combine like terms

16x^2 -48xy^3 +36y^6

What is the difference of the rational expressions below?<br> X+5/x^2-2/5x

Leviafan [203]

Answer:

$\large\boxed{\dfrac{x+5}{x^2}-\dfrac{2}{5x}=\dfrac{3x+25}{5x^2}}$

Step-by-step explanation:

$\dfrac{x+5}{x^2}-\dfrac{2}{5x}=\dfrac{5(x+5)}{5x^2}-\dfrac{2x}{5x^2}\qquad\text{use the distributive property}\\\\=\dfrac{5x+25}{5x^2}-\dfrac{2x}{5x^2}=\dfrac{5x+25-2x}{5x^2}=\dfrac{3x+25}{5x^2}$
