expand pi(8-8x^2)^2

expand

π (8 - 8 x^{2})^{2}

64 π x^{4} - 128 π x^{2} + 64 π

Solution steps

π (8 - 8 x^{2})^{2}

(8 - 8 x^{2})^{2} = 64 - 128 x^{2} + 64 x^{4}

= π (64 x^{4} - 128 x^{2} + 64)

Distribute parentheses

= π 64 + π (- 128 x^{2}) + π 64 x^{4}

Apply minus-plus rules

+ (- a) = - a

= 64 π - 128 π x^{2} + 64 π x^{4}

Rewrite in standard form

= 64 π x^{4} - 128 π x^{2} + 64 π

\frac{x ( 40 - 3 x )}{400}

2 (3 x - 8 y = - 1, 3) - 2 (5 y - 2 x = - 19)

2 (ln (3) + 1)

(x - 9) (4 x - 8 (= 0))

\frac{1}{( x + 8 ) ^{3}}
