Answer:

${x}^{2} - x + 1$

Step-by-step explanation:

subtract the functions as follows:

s(x) - r(x) = (2x+1) - (-x2 +3x)

expand the 2nd bracket by multiplying it by the negative 1 outside

= 2x + 1 + x2 - 3x

= x2 - x + 1

Voila!

How do I simplify ((3x^2+12x+12)/(2x^2+x-6))/((4x^2-9)/(3x^3+x^2-10))

Shalnov [3]

$\dfrac{ \frac{3x^2+12x+12}{2x^2+x-6} }{ \frac{4x^2-9 }{3x^3+x^2-10} } =$

$= \dfrac{3(x + 2)^2}{(2x - 3)(x + 2)} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)}{2x - 3} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)(3x^3+x^2-10) }{(2x - 3)^2(2x + 3)}$
