expand pi(19.44923-x)^2

expand

π (19.44923 - x)^{2}

π x^{2} - 122.20311 \dots x + 1188.37825 \dots

Solution steps

π (19.44923 - x)^{2}

(19.44923 - x)^{2} = 378.27254 \dots - 38.89846 x + x^{2}

= π (x^{2} - 38.89846 x + 378.27254 \dots)

Distribute parentheses

= π 378.27254 \dots + π (- 38.89846 x) + π x^{2}

Apply minus-plus rules

+ (- a) = - a

= 378.27254 \dots π - 38.89846 π x + π x^{2}

Simplify

378.27254 \dots π - 38.89846 π x + π x^{2} : 1188.37825 \dots - 122.20311 \dots x + π x^{2}

= 1188.37825 \dots - 122.20311 \dots x + π x^{2}

Rewrite in standard form

= π x^{2} - 122.20311 \dots x + 1188.37825 \dots

(3 + 5)^{10}

\frac{( - 12 x ^{2} - 324 )}{( x ^{2} + 9 ) ( x ^{2} + 81 )}

(e^{t} cos (t) + e^{t} sin (t)) d t

d y (y = 8 x^{3} + 7 5 x)

\frac{4}{x ( x - 4 )}
