expand ,900q-10w-10q(45-1/2 q)

expand

900 q - 10 w - 10 q (45 - \frac{1}{2} q)

5 q^{2} + 450 q - 10 w

Solution steps

900 q - 10 w - 10 q (45 - \frac{1}{2} q)

Expand

- 10 q (45 - \frac{1}{2} q) : - 450 q + 5 q^{2}

= 900 q - 10 w - 450 q + 5 q^{2}

Simplify

900 q - 10 w - 450 q + 5 q^{2} : 5 q^{2} + 450 q - 10 w

= 5 q^{2} + 450 q - 10 w

(x 3 + 2 x)^{2}

\frac{12 ( - 6 x ^{2} + 7 )}{( 6 x ^{2} + 7 ) ^{2}}

(1 + \frac{2 x}{n})^{3} (\frac{2}{n})

(2 + ln (x))^{2}

8 (3)^{2} + 97 (3) + 12
