expand pi(5-x^2)^2

expand

π (5 - x^{2})^{2}

π x^{4} - 10 π x^{2} + 25 π

Solution steps

π (5 - x^{2})^{2}

(5 - x^{2})^{2} = 25 - 10 x^{2} + x^{4}

= π (x^{4} - 10 x^{2} + 25)

Distribute parentheses

= π 25 + π (- 10 x^{2}) + π x^{4}

Apply minus-plus rules

+ (- a) = - a

= 25 π - 10 π x^{2} + π x^{4}

Rewrite in standard form

= π x^{4} - 10 π x^{2} + 25 π

(x^{3} - 3 x^{2} + 4) d x

3 (3 x - 1 = 4)

\frac{6 - 11 x}{( 3 x - 1 ) ( x + 2 )}

\frac{π ( 2 - ln ( 3 ) )}{2}

\frac{2 ( u + x ) ^{2}}{x ^{2}}
