expand ((49x+5)(49x-5))/(49)

expand

\frac{( 49 x + 5 ) ( 49 x - 5 )}{49}

49 x^{2} - \frac{25}{49}

Solution steps

\frac{( 49 x + 5 ) ( 49 x - 5 )}{49}

Expand

(49 x + 5) (49 x - 5) : 2401 x^{2} - 25

= \frac{2401 x ^{2} - 25}{49}

Apply the fraction rule:

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

\frac{2401 x ^{2} - 25}{49} = \frac{2401 x ^{2}}{49} - \frac{25}{49}

= \frac{2401 x ^{2}}{49} - \frac{25}{49}

Divide the numbers:

\frac{2401}{49} = 49

= 49 x^{2} - \frac{25}{49}

(a^{\frac{1}{2} + b})^{8}

e^{y} (- e^{- y} + y)

\frac{4 x ^{2} - x - 2}{( x + 1 ) ( y + 1 )}

- 2 (1 + a^{\frac{1}{2}} x + a y)^{2}

\frac{5 ( 3 x - 2 )}{3 x - 6}
