expand (21x^2-5)/((7x-5)^2)

expand

\frac{21 x ^{2} - 5}{( 7 x - 5 ) ^{2}}

\frac{21 x ^{2} - 5}{49 x ^{2} - 70 x + 25}

Solution steps

\frac{21 x ^{2} - 5}{( 7 x - 5 ) ^{2}}

(7 x - 5)^{2} = 49 x^{2} - 70 x + 25

= \frac{21 x ^{2} - 5}{49 x ^{2} - 70 x + 25}

3 (\frac{- 75 x ^{2} + 264 x + 48}{16} + 6)

(z - 1) (z - e^{- T} cos (T \cdot 35))

s (s^{2} + 8)

- \frac{35}{( 5 )}

- 2 x \cdot (x - \frac{2}{3}) + x - \frac{2}{3}
