simplify ((-12.921x^2-25.842x+4380))/((x+1)^2)-20

simplify

\frac{( - 12.921 x ^{2} - 25.842 x + 4380 )}{( x + 1 ) ^{2}} - 20

\frac{- 32.921 x ^{2} - 65.842 x + 4360}{( x + 1 ) ^{2}}

Solution steps

\frac{- 12.921 x ^{2} - 25.842 x + 4380}{( x + 1 ) ^{2}} - 20

Apply the fraction rule:

a + \frac{b}{c} = \frac{a c + b}{c}

= \frac{- 20 ( x + 1 ) ^{2} - 12.921 x ^{2} - 25.842 x + 4380}{( x + 1 ) ^{2}}

Simplify

- 20 (x + 1)^{2} - 12.921 x^{2} - 25.842 x + 4380 : - 32.921 x^{2} - 65.842 x + 4360

= \frac{- 32.921 x ^{2} - 65.842 x + 4360}{( x + 1 ) ^{2}}

(6 - x + 4)^{2}

\frac{( x + 3 ) ^{2}}{4}

(x + 3) (x + 3)^{3}

\frac{1 - e ^{- λ (t + x)}}{1 - e ^{- λ t}}

(x - 2) \cdot e^{x}
